The Impact

This study used the multivariate analysis of variance (MANOVA) test statistic to examine the impact of three categories feed used in the production of pig in Delta State. The multivariate test statistic considered are the Pillai – Bartlett trace, Wilks’ Test Statistic, Roy’s Largest Root Test Statistic, and the Lawley- Hotelling (LH) Statistic. The objectives include to: evaluate the robustness of the four Multivariate Analysis of Variance test statistics to ensure that the best is employed in multivariate analysis to guarantee most useful result in pig production; determine the relatively efficient test statistic for pig production; and determine the test statistic that is consistent across the sample sizes. Secondary source of data collection was used to obtain the data required for the analysis. The outcome of the study showed that the obtained data was multivariate normally distributed based on the result of the asymmetry-based multivariate normality test and the multivariate normality test based on the kurtosis test which makes the data suitable parametric multivariate method such as multivariate analysis of variance (MANOVA). The results show that the Wilks and Roy tests found a significant difference for the intercept. While the Pillai and LH tests could not find any significance. The Roy test was also found to be significant for feed one, feed two, and feed three. The Wilks and Roy tests also turned out to be significant differences for the intercept. All test measures showed significance for feed one. The Wilks and Roy tests also showed a significant difference for feed two, while all test measures found a significance for feed one. Another result showed that none of the tests found significance for the interaction between feed one and two, while the Roy test found significance for the interaction between feed one and three, feed two and three and feed one, two and three. The performance of the test for evaluating the performance of feeds for pig production with/without considering interactions was found to be in the following order of magnitude: Roy, Wilks and Pilla = LH. This result implies that the Roy method, with or without consideration of the interaction, has a better performance of the test than the other methods considered in the study.

Background: The cognitiveCognitive dysfunction may be an important factor in smoking and nicotine abuse. However, there are very few studies that have examined the effects of psychiatric conditions on the cognitive flexibility of smokers. Objectives: This research was conducted with the aim of examination theto examine cognitive flexibility (perceive theperceived controllability and cognitive alternatives) ofamong smokers in the context of with social anxiety. MaterialMaterials and methods: The research was a study withpresent causal-comparative design. The populationstudy was allconducted on 60 smoker students ofstudying at Arak University, Arak, Iran, in 2018-2019 years. For selecting the research sample the. The study population was selected using the purposive sampling was usedtechnique. At first, the participants completed the Social Phobia Inventory (SPIN) and Cognitive Flexibility Inventory (CFI).. Then, based on the cutoff point scores of SPIN (19 to above),≤), the participants were divided into two smoker groups (n=30 in each group) were selected: smoker groupsof smokers with and without social anxiety. (n=30 in each group). Finally, these groups were compared in perceive the terms of perceived controllability and cognitive alternatives by Multivariate Analysis of Variance (MANOVA).using the multivariate analysis of variance. Results: The results indicated a significant difference in the linerlinear composition of the dependent variables ofin the two groups (wilks,Wilks’ lambda= 0/.799, F50,2= 6/.726, p= P=0/.004). UnivariateThe results of the univariate analysis of variance indicated that the smoker group with social anxiety had lower perceive theperceived controllability and cognitive alternatives, compared to the smoker group without social anxiety. Conclusion: In generalAs the findings indicated, the level of cognitive flexibility in the smokers with and without social anxiety iswas different. Therefore, it is necessary to consideringconsider the evaluation and treatment of cognitive deficits in smokers based on their level of social anxiety.

In a series of high-gradient streams along the Wasatch Front in northern Utah, perlid stoneflies were more abundant in benthic samples from 14 fishless streams than in 9 similar streams which contained trout. Smaller-bodied perlodid stoneflies were more abundant in samples from streams containing trout. Herbivorous insect abundances varied substantially within groups of streams containing and lacking trout; multivariate analysis of variance using the six most abundant herbivorous taxa indicated no significant difference between the two groups of streams. Similarly, total numbers of invertebrates did not differ between streams with and without fish. Sites above and below the upstream limit of trout in three streams showed patterns in invertebrate abundances similar to that seen at the whole-stream scale. Trout may have no effect on the overall density of stream benthos because of their negative direct effects on invertebrate predators.

Morphometric analysis of some populations of lymnocardiid species (Mollusca: Bivalvia) from Razelm Lake Complex (Romania) In this paper we report the morphometric analysis of some populations of Lymnocardiid species from the lakes Razelm and Goloviţa. We used three measurements ratios to perform a discriminant analysis and a multivariate analysis of variance (MANOVA), in order to compare the species Hypanis colorata vs. Hypanis angusticostata in the two lakes, H. colorata in Razelm vs. Goloviţa, and H. angusticostata in Razelm vs. Goloviţa. From this analysis we concluded that the multivariate means of the morphological variables used in this study were highly significantly different (p=3.2e-05) between the two species. Concerning the geographical variability, in both species, the analysis showed no significant difference between the populations in the two investigated lakes. We also determined from a fitting curve analysis, that the growth pattern of both species shows length-height isometry and width-length and width-height negative allometry.

A literature review indicated little research on punishment in work settings despite the prevalence of punishment as a control technique. In the current study, 45 female supervisors and 36 male supervisors rated a list of 40 job-related behaviors as to the intensity of discipline they would administer to a subordinate who did any of the job-related behaviors. A multivariate analysis of variance of the ratings indicated no significant difference associated with sex of the rater as to the intensity of the discipline they would administer. Nonsignificant correlations were noted on disciplinary intentions with increasing age, tenure, and number of subordinates. These findings, along with other studies of sex differences in the work force, indicate such study of sex differences may need to be limited to a narrow field in which sex differences have been reported, such as perceived stress.

Background: Immigration can be accompanied by many psychological outcomes for emigrant families. Objectives: The present study aimed to compare family drawing test indices and behavioral problems among Iranian and Afghan emigrant children. Methods: The research design was a comparative and cross-sectional study. We included 550 Iranian and Afghan students aged 7 - 11 years in Isfahan Province from April to June 2017. Achenbach Behavioral Problem questionnaire (2001) was sent to their mothers for filling, and Drawing Family Test was conducted. After reducing the number of dropout students, the final sample reached 282 students (including 174 Iranian students and 108 Afghan immigrants)., SPSS-23 software and chi-square tests as well as multivariate analysis of variance were used for analyzing data. Results: The results of the chi-square test showed that there was a significant difference in some of the drawing indices, including size, rhythm, location of drawing, valuation, removal of person, and distances between two groups of Iranian students and Afghan migrants (P < 0.05). Also, the results of multivariate analysis of variance indicated that there was a significant difference among mean scores of behavioral problems and dimensions of somatization, thinking problems and anti-social problems in the two groups (P < 0.05). There was no significant difference in other variables. Conclusions: According to the results, the children of the Afghan refugee group have more both behavioral problems and drawing indices than the Iranian group.

В статті розглядаються особливості застосування стимуляторів росту компанії «Soil-Biotics» (США) як приклад комплексного використання гуматів для підвищення рівня врожайності пшениці озимої. Доведено, що норми та способи використання гуматів для передпосівної обробки насіння та внесення в ґрунт сприяють кращому формуванню елементів структури врожайності, в першу чергу продуктивного кущіння. Статистична обробка методом багатофакторного дисперсійного аналізу засвідчила, що варіанти, де використовувалася передпосівна обробка насіння препаратом «1R Seed treatment» в нормі 3 кг/т та вносився в ґрунт «5R SoilBoost EA» в нормі 30 кг/га, значно перевищували контроль за кількістю рослин, які краще перезимували та продуктивністю. Аналіз впливу гумінових препаратів на формування ознак продуктивності показує, що внаслідок передпосівної обробки насіння та внесення під час сівби гумінового препарату «5R SoilBoost EA» продуктивне кущіння збільшується майже на 37 %. Інші ознаки реагують на застосування препаратів менше – кількість зерен в колосі зросла на 7,3 %, а маса зерна з колоса – на 5,5 %. Проте така різниця була статистично достовірною порівняно з контрольними варіантами. Маса 1000 зерен при цьому залишалася фактично незмінною – статистично достовірної різниці між варіантами не було. The article discusses the features of the use of growth stimulators by Soil-Biotics (USA) as an example of the integrated use of humates to improve the yield of winter wheat. It is proved that the norms and methods of using humates for presowing seed treatment and introduction into the soil contribute to a better formation of the elements of the yield structure, primarily productive tillering. Statistical processing by the method of multivariate analysis of variance showed that the variants in which presowing seed treatment with 1R Seed treatment was applied at a rate of 3 kg / t and applied to the soil 5R SoilBoost EA in the norm of 30 kg / ha, significantly exceeded the control by the number of plants , which were better wintered and productive. Analysis of the effect of humic preparations on the formation of signs of productivity shows that as a result of presowing seed treatment and application of humic preparation 5R SoilBoost EA during sowing, productive tillering increases by almost 37%. Other signs respond to the use of drugs less - the number of grains in the ear increased by 7.3%, and the mass of grain from the ear - by 5.5%. However, this difference was statistically significant compared to the control options. The mass of 1000 grains remained virtually unchanged - there was no statistically significant difference between the variants.

This study examines the expression of selflessness – the tendency to ignore one’s own needs and serve others’ needs – in Rorschach protocols of women suffering from anorexia nervosa. The protocols of 35 women suffering from anorexia nervosa were compared to 30 protocols of a psychiatric comparison group. A multivariate analysis of variance over five variables (AG, PER, PHR, COP, and GHR) was significant: Anorexic patients showed higher characteristics of selflessness compared to the psychiatric comparison group. These findings contribute to the validation of the Rorschach technique and to the clinical observation of selflessness in anorexic patients, and they emphasize specific characteristics in the treatment of anorexia nervosa patients.

Interactions of attention and verbalization were investigated for effects of self-reported arousal and state-anxiety. Levels of verbalization from silence through talking-without-a-listener to disclosure were compared while self-directed attention was manipulated for sensation versus general thoughts and feelings. Following a stimulus, disclosure of sensations was expected to reduce state anxiety and increase energetic arousal significantly more than disclosure of thoughts. Based on a randomly assigned sample of 120 men, a 3 × 2 × 2 multivariate analysis of variance indicated a significant interaction in the predicted directions. A significant interaction was also found for the 3 × 2 interaction for energetic arousal. For state anxiety means were in the predicted direction. Results indicate that verbalization of sensations is more energizing and calming than silence, while for general thought, silence is more energizing and calming than verbalization. The results suggest efficacy in reframing self-talk to quiet awareness and in communicating sensed distinctions as they emerge.
