EVALUATION OF IRRIGATION REGIME ON TOMATO IN SHEBEDINO WOREDA, SIDAMA REGION, ETHIOPIA [PDF]
Aregash Deboch, Worku Nigussie, Zemede AmadoIrrigation knowledge that saves water is essential to convince the economic and environmental sustainability of commercial agriculture. Accurate irrigation scheduling is serious to improving irrigation efficiency. A field experiment was conducted to evaluate the responses of tomatoes to irrigation regimes (when and how much) and to identify water productivity under optimal irrigation regimes. The study was conducted for two consecutive years at Hawassa Agricultural Research Center, Ethiopia. Four irrigation scheduling (125% MAD, 100% MAD, 75% MAD, and Farmer practice were used. The design of the experiment was arranged in Randomized Complete Block Design (RCBD) which has four replications. Roma VF variety of tomato was used for this experiment. Results showed that tomato marketable, total yield, and water productivity were significantly affected by irrigation scheduling. The highest marketable tomato yields of 42750kg/ha were obtained from treatment 75%MAD irrigation scheduling. The lowest marketable tomato yield of 25250kg/ha was obtained from treatment Farmer practice.
However, from economic analysis results, 100% MAD irrigation scheduling had a better marginal rate of return (5337.5). Therefore, based on the current findings, the application of irrigation scheduling for tomatoes in the study and similar agro-climatic area and soil type application of irrigation scheduling at 100% MAD gives the highest tomato yield and water use efficiency.
Keywords: Irrigation Scheduling, RBCD, MAD, and Water Use Efficiency.

Nandisha Ganiga, Hemaraja Nayaka, Sharanya J Shetty, Vaishnavi L Shetty, Satish KumaraswamyAphasia refers to a family of clinically diverse disorders that affects the ability to communicate by oral or written language due to brain damage .The present study is aimed at investigating about the differences in verbal fluency between the typical group and individuals with aphasia.
The study objectives were the comparison of frequency , cluster ,cluster size , cluster ratio in semantic verbal fluency tasks. The verbal fluency tasks (‘animal’ , ‘vegetables’ and ‘vehicles’) between two groups i.e., the typical population and individuals with aphasia were compared. The study findings showed that verbal fluency scores for typical individuals were greater than that for individuals with Aphasia.
Hence, the finding implies that the typical population had better performance than the clinical population due to their intact neurological structure and physiology.
THE CONTRIBUTION OF TEACHERS JOB SATISFACTION ON THEIR JOB PERFORMANCE IN SECONDARY SCHOOLS IN TANZANIA [PDF]
Aziz Ayoub NgwaleThe study investigated the level of the contribution of teachers’ job satisfaction on teachers’ job performance in Tanzania secondary schools. The field work covered six secondary schools in two Districts in Ruvuma region – Tanzania namely Songea municipality and Songea district council. Data was collected through a questionnaire and was analysed using linear regression analysis. The results indicated that there was significant contribution of teacher’s job satisfaction on teacher’s job performance. Further, when the independent variables involved to describe teachers job satisfaction considered separately, job security was found to have high significant contribution on teachers job performance, followed by communication which has significant contribution, then independence which has insignificant contribution and finally work condition which has significant contribution. It was recommended that, since job satisfaction has significant but low impact on teachers’ performance, the other aspects rather than satisfaction have to be considered including motivation, human resource management and supervision, setting target to reach and measures to be taken, training and workshop for improvement of teacher’s job performance. Key words: job performance, job satisfaction, teachers’ job performance and teachers’ job satisfaction.

The Effects of Shrimp Shell Extract Addition in Feed to Growth and Survival Rate of Sangkuriang Catfish (Clarias gariepipnus) [PDF]
Kiki Haetami, Muhammad Farras, Ayi Yustiati, Roffi GrandiosaThe availability of feed ingredients, such as fish meal and soybean meal, is increasingly limited. Feed makers then use various methods to deal with this, one of which is through the addition of synthetic amino acids or alternative materials to feed, both as source of protein in feed ingredients or as feed additives. Shrimp shell extract from the bio-processed microbes (Bacillus licheniformis, Lactobacillus sp., and Sacharomyces sereviseae) is one of the materials that can be used as feed additive because it can improve protein quality in feed. The purpose of this research was to determine the optimal dose of shrimp shell extract addition to feed by observing the use of it on the growth and survival rate of Sangkuriang catfish (Clarias gariepinus). The research was conducted in April – May 2021. The research was carried out at the Education Laboratory, Faculty of Fisheries and Marine Sciences, Padjadjaran University, Jatinangor. The method used was experimental method of Completely Randomized Design with four treatments and three replications, analyzed using Analysis of Vari-ance (Anova), and as significant difference was found, then proceeded with the Duncan's Test at a level of 5%. The results showed that the addition of shrimp shell extract showed a significant difference (p<0.05) on the growth rate. All treatments resulted in a survival rate of 100%, the highest growth with the addition of shrimp shell extract at a dose of 5ml/kg was 4.63 ± 0.05% and the lowest was in the con-trol (commercial feed without the addition of shrimp shell extract) 4.4 ± 0, 08%. Based on the research results, it can be concluded that the addition of shrimp shell extract at 5 ml/kg to the feed can increase the growth of Sangkuriang catfish (Clarias gariepinus).

Michael Peter Owiny, Betty Ezati, Badru Musisi &Aida Nyenje. LAssessment of learners is one of the key determinants for quality of education for any nation. Continuous pursuits for improvement in quality of assessment progressively led education practitioners at different levels to use varying strategies. In Uganda for instance efforts towards improving assessment has been done with emphasis on application non- discrimination of learners at different primary school class levels. The Government Uganda particularly increased opportunities for equal assessment through providing assessment materials to every learner and competent teachers deployed to support learners at various levels of assessment. Infrastructure development initiatives undertaken to reduce assessment imbalances arising from crowded classroom and lack of space. Changes in policies that encouraged skilled based and continuous assessment made and utilized. However, such efforts notwithstanding assessment outcomes in Ugandan primary schools especially Lango Sub Region. Therefore, examined the influence of democratization of education on learners’ assessment in Uganda with specific reference to Lango Sub region.
Slums in Casablanca: Assessment of the VSB program, case study:
Er-hamna Slum [PDF]
Sakina Boufarsi, Behiye Isik Aksulu, Mehmet Emre AysuThe Cities Without Slums Program (VSBP) is Morocco's most well-known slum clearance
initiative. It was established in 2004 on royal orders, following terrorist assaults on the country's
economic center, Casablanca, in 2003. The slum clearance effort has resulted in a 66 per cent
relocation rate. This rapid reduction in slums earned the Moroccan Ministry of Housing and Urban
Development and Al Omrane Holding (both significant players in the VSBP), the UN-Habitat
Award of Honor in 2010. Nonetheless, slums continue to resist in major cities such as Casablanca.
Slums in Casablanca are a response devised by the impoverished as a result of government
bureaucracy and failed housing policies; they show governments' inability to respond to urban
development's need for appropriate housing for the vulnerable people. This problem will be
addressed by looking back at prior techniques and examining the benefits and drawbacks of the
most current VSB Program. One of these flaws is the inability of mechanisms intended for slum
dwellers to gain access to property ownership, the concentration on clearing land rather than
establishing new communities, and the-one-size- fits -all strategy. Afterwards, the focus is placed
on whether enhancing physical housing comfort is a significant element in people's improvement
of their living conditions. Using an in-depth analysis through Er-hamna slum to explore the
suitability of these options regarding the overall situation of the slum dwellers and assessing people
attitudes towards resettlement, and therefore to direct improved and valuable recommendations to
address the slum problem.

ADVANTAGES OF CANNED PACKAGING ON FISHERY PRODUCTS [PDF]
Maulana Asyrofi Najib and JuniantoIndonesia as a maritime country should be able to further develop the fisheries sector. Fish is a perishable food source, so it needs to be processed quickly and accurately currently, canned fish products have been widely circulated in the free market, including those found in supermarkets and traditional markets. Not only home industries have produced canned fish, but also large industries. The existence of canned fish began to be known to the public, although not widely. Therefore, a literature review is needed regarding the potential and advantages of canned packaging in fishery products. The results of this literature review are expected to present further experimental research related to the use of canned packaging in fishery products that have a better impact on fishery products and consumers. The results of the review article that has been done show that fishery products that can be packaged in cans according to several previous studies include milkfish, African catfish fillet, tuna, sardines, skipjack tuna, gray tuna, lemuru fish, and tembang fish. In canned fish products, the pH value is influenced by many factors, a decrease in the pH value occurs in smoked Dumbo Catfish Fillet from 6.80 to 5.47, then Chela Fish from 6.8 to 5.9, in tuna fish from 5.97 to 5.91. Then the water content of milkfish is 59.41% and canned sardines is 10.25% and ash content is 2.46%.

Political connection, Firm performance and tax benefits: Pakistan Evidences [PDF]
Abdul Rehman Rauf, Haris Ali, Amir Liaqat, Shabbir HussainIt is a broad concern that tax benefits and firm performance depends not only on the mangers ability to exploit the market of the economy but also on the success ability of political markets. This paper performs an investigation on the political effect on firm performance towards enterprises SEOs and private enterprises. We utilize the information of Pakistani recorded firms from 2014 to 2020, and we found that politically associated administrators of private firms outflank without such chiefs whose neighborhood SOEs fail to meet expectations without such supervisors. We tracked down that some private firms, which are politically related supervisors inclined or serious issues of over financial backers. This study resolves the mixture of findings with the previous literature on political connections impact on the frim performance and tax benefits.
Review on parasites of commercially important tropical fishes: - Characteristics, Distribution, risk factors and Prevention approaches [PDF]
Marshet Adugna Mitiku and Dawit AdisuThis review has been made with the objectives of compiling the nature and characteristics of the most common fish parasites in the tropical regions of the world. The review was made with a collection of published articles in the area of fish parasitology in tropical regions of the world. Fish parasites are important components of host biology, population structure and indeed ecosystem functioning. They can be found in any fish species and within any type of aquatic and culture system. They range from protozoans such as flagellates, ciliates, and apicomplexans to metazoans including myxozoans, trematodes, cestodes, acanthocephalans, nematodes, and crustaceans. Over 40% of all known species on earth are parasitic with parasitism being ubiquitous in some taxa and either absent or rare in others. The knowledge of the status of parasite diversity in the tropics is still inadequate. Parasitic infestation frequently occurs in fish that causes retarded growth rate, reduced production, consumer rejection, low reproduction and mass mortality in fish. The most common symptoms of parasitic infestations in fish are weight loss, disruption of reproduction or impotency, blindness, abnormal behaviour, epithelial lesions, deformities of gills and others. These all eventually cause an economic loss in the fish farming sector and hence parasites are among the important factors responsible for production losses but fish parasites may be present in or on fish in subclinical state or carrier state and do not always cause disease in fish. Therefore, it is essential to conduct research on the major fish parasitic pathogens which will help for future aquaculture productivity and other environmental functions of the fish parasites in the aquatic environment.
MODELING OF MEMBRANE REACTOR FOR METHANE STEAM REFORMING: AN ALTERNATIVE TO CONVENTIONAL REACTORS [PDF]
Jackson Gunorubon Akpa, Kennedy Raphael, Adeloye Olalekan Michael, Abowei M.F.N.Steam reforming which accounts for over 50% of hydrogen production is limited by thermal equilibrium. Frequent occurrences in conventional tubular steam reformer are sintering of catalysts, hot spots and hot-bands on tubes and low methane conversion. To overcome the equilibrium limitation of methane reforming, a membrane steam reformer is suggested whereby the production and separation of synthesis gas is consolidated in one system. In this study, 1-D steady state models were developed to predict the performance of methane steam reforming reaction in a membrane reactor. To evaluate the kinetics of membrane steam reforming of methane, the widely accepted Xu and Fromment equations were employed. MATLAB ODE23s solver which implements the 4th order Runge-Kutta algorithm was useful in obtaining solutions to the developed models. Effects of changing parameters such as inlet temperature, steam to gas ratio and membrane thickness, were investigated. Simulation studies carried out in this research revealed that performing reforming of methane in membrane type reactor can lead to 99% reactant conversion at moderate temperature (500-600 oC). Using input parameters of a conventional steam reformer (inlet temperature and pressure of 530oC /29bar respec-tively) resulted in a methane conversion and hydrogen yield of 73.6%/2.7 respectively. Model results showed a 21.6% increase of methane conversion in membrane reactor against a conventional steam reformer. The results were validated with  and deviations of 2% (methane conversion) and 9% (hydrogen yield) were recorded. Hydrogen yield reached 3.5 at an optimal temperature of 590 oC.

OlobiaInformation and knowledge in knowledge management creates polarity and subservience in their utilization, storage, and distribution biased against information because it is always believed that the creation and management of knowledge determines organizational success far beyond information processing.
This paper argues that the confluence of information and knowledge uptake in a highly globalized society should be the new paradigm where parallel functions of the two ensure systems approach management recognizing both as inseparable and interdependent ele-ments and the creation of an information and knowledge culture in an organization is recognized as the dictum of optimal organiza-tional management.
Robust Ridge Regression Estimators for Handling Multicollinearity and Outliers in Linear Regression Models [PDF]
Tijjani Adamu, Yusuf Mohammad, Adeniyi Ogunmola Oyewole, Nicholas P. DibalIn multiple linear regression analysis, the ordinary least squares (OLS) method has been the most popular technique for estimating parameters of linear regression model due to its optimal properties. OLS estimator may fail when the assumption of independence is violated. This assumption can be violated when there is correlation between the exploratory variables. In this situation, the data is said to contain multicollinearity and eventually will mislead the inferential statistics. However, the problem becomes more complicated when there are abnormal observational data known as outliers. Multicollinearity and Outliers are two main problems. When multicollinearity exists, biased estimation technique Ridge Estimator are preferable to OLS. On the other hand, when outliers exist in the data, robust estimator like LTS Estimator, are preferred. To handle these two problems jointly, the study ussed Robust Ridge Regression estimator. This study aims to examine the performances of four estimators of multiple linear regression model with combined problems of multicollinearity and outliers. The performance of the four estimators, namely the Ordinary Least Squares (OLS), Ridge Regression (RIDGE), Least Trimmed Square (LTS) and a robust ridge regression estimator based on Least Trimmed Square estimator (RIDGE LTS) are compared using mean square error as criteria for assessment. For this purpose, a simulation data with p = 3; n = 25, 50,100; and full multicollinearity (r = 0.90, 0.95, 0.99) and outliers (0%, 20%) was used. The existence of multicollinearity was evaluated using VIF value. The empirical evidence shows that RIDGE LTS is the best among the four estimators for degree of multicollinearity and number of outliers and is more efficient because it has the smallest MSE than LTS and RIDGE in any samples sizes.
EFFECTS OF GROUP CONTINUOUS ASSESSMENT INSTRUCTIONAL APPROACH ON MATHEMMATICS ALGEBRA: THE CASE ACHEIVEMENT SECOND YEAR CANDIDATE TEACHERS [PDF]
The objective of this study was to investigate the effects of group continuous assessment strategies on candidate teachers’ academic achievement and attitude towards modern algebra (Mathematics). Group continuous assessment strategies as a preferred continuous assessment methods were tested and proved as stated in the result section of this research. The study was conducted at Giggle Beles College of Teachers Education (GBCTE) on second year mathematics stream candidate teachers. Three intact sections were taken and candidate teachers’ are grouped into 4 according to their mathematics group point Average (GPA) taken from the registrar of the college and each group is formed systematically according to their achievement level. In the study, data were obtained through the use of quasi experimental group model. Two types of instruments were used for measurement: achievement tests and survey method using five Likert scale questionnaire to know candidate teachers’ attitude towards Modern Algebra due to the effect of group continuous assessment. Pilot study was carried out on 20 candidate teachers of the same background taken from other College of Teachers Education (CTE) but not in the sample group to test the reliability of the questionnaire items and achievement test items. The calculated Cronbach alpha coefficient result was greater than 6.5 for each questionnaire and GCA test questions. The data obtained from the three intact sections and all groups result were analyzed using SPSS window 16.0. Descriptive statistics, mean and standard deviation were used to describe candidate teachers’’ achievement test scores and their questionnaire responses. Meanwhile, multiple regressions were used to analyze the contribution of continuous marks to final grades of candidate teachers’; ANOVA also used to analyze significant differences in the assessment marks. Each intact section was grouped into four and treated with four GCA strategies and one test after the treatment of each GCA Strategies and with one final examination independently. Likert scale was used to know students' attitude towards modern algebra. Results in table 5 and 8 indicated that implementing GCA strategies improved candidate teachers’’ academic achievement in modern algebra and attitude towards modern algebra. Candidate teachers developed positive attitude towards GCA strategies, their academic achievement and attitude towards modern algebra were positively correlated. At college level other teachers are encouraged to implement GCA methods of continuous assessment for their candidate teachers in the teaching of mathematic concept.

Tunde Kelani’s The Narrow Path: An Approach to Feminist Discourse [PDF]
ADESEKE ADEFOLAJU EBEN (PhD),AYEOBA GBENGA ALEXNigerian Home Videos and Films have become a colossal imprint entity that dictates the pace for African films. Many film producers, no doubt, have contributed immensely to this tremendous growth. However, one towering figure who has contributed significantly to this phenomenal image of Nigerian film industry is Tunde Kelani. TK, as he is popularly called, has affected positively the content, language and pictures of Nigerian Film Industry. Many of TK’s films have been critically examined and analyzed along the line of language, lexis and moodand style but the feminist angle to his works has not been thoroughly explored. Hence, the significance of this paper. Tunde Kelani has shown through his films that he is unapologetically a feminist through the treatment and roles he gives to women in his films such as Arugba, Maami, The Narrow Path and others.Unlike some other Nollywood film producers, TK has adorned women with pride, honour and gait, though, he equally lampoons and discredits exuberance and negative attitudes. His film, The Narrow Path which is the object of the current research is exceptionally crafted and is one of his best in the promotion of feminist views, moral values, etiquette, cultural balance and nemesis. This paper discusses how all the above items are portrayed in the film. It is our opinion that filmmakers, in Africa, especially in Nigeria should take a cue from the innovations and trends in TK’s films in order to further enhance the positive image of African films.
EFFECT OF METACOGNITION ON SECONDARY SCHOOL STUDENTS’ INTEREST IN MATHEMATICS IN GWER-EAST LOCAL GOVERNMENT AREA OF BENUE STATE [PDF]
Abari, M.T. and Tyovenda, T.M.The study on effect of metacognition on secondary school students’ interest in mathematics in Gwer-East Local Government Area of Benue State was an attempt to ascertain the effect of metacognitive strategy on students’ interest in mathematics and to determine the effect of metacognitive strategy on male and female students’ interest in mathematics. The study used a quasi-experimental design. 120 senior secondary one student (SSS1) were used. The experimental group were expose to metacognitive teaching approach while the control group were taught using the conventional method. The instrument used for data collection was Metacognitive Mathematics Interest Inventory (MMII) with a reliability coefficient of 0.83 using Cronbach’s Alpha. Two hypotheses were formulated and tested at 0.05 level of significance. Analysis of Covariance (ANCOVA) was used to test the hypotheses. Results from the study revealed that the students taught mathematics using the metacognitive teaching approach showed higher interest in learning mathematics than the students in the conventional method group. The study also revealed that both the male and female students in the experimental group had interest in mathematics.
