Studies on writing, thus, become crucial because when students make the transition from Secondary School to a Tertiary Institution, they encounter many challenges. One of them is the writing of B.A projects. Most of these undergraduate students both in L1 (English as a first language) and L2 (English as a second language) still find it difficult to argue, discuss or evaluate competently as well as persuasively in English essay writing. The present study aimed at exploring metadiscoursal choice and its influence on the success of students’ academic writing. The study was conducted within the framework of Appraisal Theory. The data was randomly generated from the written essays by thirty selected Level 400 students both from Umaru Musa Yar’adua University and Al-Qalam University Katsina. Also, the data was descriptively alaysed and presented. It was discovered that six (6) of the essays do not contain the relevant elements for this study, thus excluded from the analysis. To achieve the main objective of this study, the first six categories of the most successful essays and the least successful ones were taken for in-depth analysis. They were analysed paragraph by paragraph and then each interactional metadiscourse element was separately discussed as a whole. The findings showed that many of the students were not exposed to these elements, thus, they write academic essay the way they speak. It is against these findings that the present study unravels that embedding the teaching of metadiscourse in cumulative learning practices could consequently empower students to develop both linguistically and intellectually.

This study measured Saudi university students’ receptive vocabulary knowledge towards the end of their final semester. The subjects were 71 Saudi male and female students. The Vocabulary Levels Test, adopted from Nation’s (2008), was administered in this study. The test assesses learners’ receptive knowledge of word meaning at the following distinct vocabulary levels: the 2nd 1,000-word level, the 3rd 1,000-word level, the 5th 1,000-word level, the 10th 1,000-word level, and the Academic Word List (AWL). The results showed different participants’ performance at different word levels with decreasing mean scores as the frequency of word levels decreased. The results also showed, with no exception, that males outperformed females with statistically significant differences in all the five sections of the test. The participants’ average vocabulary size is approximately 876 and 799 words in the 2nd 1,000-word level, 436 and 355 words in the AWL, 725 and 590 words in the 3rd 1,000-word level, 580 and 477 words in the 5th 1,000-word level for males and females respectively. However, the average vocabulary size decreased dramatically in the 10th 1,000-word level to 254 words for males and 124 for females. Based on these findings, it is concluded that Saudi English Language and Translation university graduates, even with large vocabulary size in the high frequency bands, are generally still below the level of the desired vocabulary competency as EFL learners, and are in fact, in need for more support and concentration in their undergraduate study with regard to their vocabulary learning.

This study inspects the relationship between language learning strategies (LLS) of 905 Jordanian high school ELL students and their vocabulary size. The data are collected through two instruments: First, a questionnaire of 35 items and 3 types of strategies (metacognitive, cognitive, and social-affective strategies) were adapted from the Strategy Inventory Learning (SILL, Version 7.0) by Oxford (2005) to evaluate language learning strategies. Second, the Vocabulary Levels Test (VLT): Version 2 by Schmitt (2001) to gauge the vocabulary size by measuring the 2,000 word-level, 3,000 word-level, 5,000 word-level, 10,000 word-level, and Academic Word (AWL) level of the students. The results of the descriptive analysis revealed that the students’ overall LLS was at a moderate strategy use. Concerning their use of strategies, the most used strategies were metacognitive, followed by cognitive strategies, and the least used strategies were social-affective strategies. In addition, the effect of their vocabulary size on the use of LLS was identified. Students with high vocabulary size applied more language learning strategies and specific strategies more than students with low vocabulary size. The students’ use of LLS had a positive and significant correlation with their vocabulary size. Students with higher vocabulary size were able to employ strategies to manage and control their learning, in addition, to observe their learning better than students with lower vocabulary size. All together for students to be better in learning English, they are required to enhance their vocabulary because of its substantial relationship with language learning strategies.

Although brainstorming strategy is not a new concept, the practice is relatively new in the Arab region, especially, in Jordan, where the old approaches are still widely used. This qualitative study examined the attitudes of Arabic language lecturers at Language Center, University of Jordan towards utilizing brainstorming in their instruction. With the help of convenience sampling, ten lecturers were selected to participate in the study. To reach a clear understanding of this issue, the study utilized a qualitative design and semi-structured interviews and observations were used as a tool to collect the data. The findings revealed that the attitudes and the actual use of brainstorming strategy by ASOL lecturers in their instruction were generally positive. A key recommendation of the study is that further research needs to be conducted into the reasons why some instructors opt not to use brainstorming strategy in their instruction.

The current study aimed at examining the influence of tourism marketing strategies within the Jordanian 5 stars hotels. The researcher has chosen the self-administered questionnaire to form the tool of the study on a sample of the marketing and promotion managers from the 5 stars hotel in the capital of Jordan- Amman. The total number of the hotels which took part in the study was (27) 5 stars hotel located in Jordan. The results of the study indicated that political, social and economic stability in addition to the systematic promotion of cultural events appeared to be the most influential factors on the tourism marketing strategies within the studied hotels. The least influential factors appeared to be brand position, the service quality and the facilities. This was attributed to the current status of the Middle Eastern countries and the fact that the political stability is what drives tourists to the destination. The study recommends the ability of the government to deal with political and economic challenges such as poverty and unemployment impinges on the trust of potential tourist.

In this work, we study the two-parameter Odd Lindley Weibull lifetime model. This distribution is motivated by the wide use of the Weibull model in many applied areas and also for the fact that this new generalization provides more flexibility to analyze real data. The Odd Lindley Weibull density function can be written as a linear combination of the exponentiated Weibull densities. We derive explicit expressions for the ordinary and incomplete moments, moments of the (reversed) residual life, generating functions and order statistics. We discuss the maximum likelihood estimation of the model parameters. We assess the performance of the maximum likelihood estimators in terms of biases, variances, mean squared of errors by means of a simulation study. The usefulness of the new model is illustrated by means of two real data sets. The new model provides consistently better fits than other competitive models for these data sets. The Odd Lindley Weibull lifetime model is much better than \ Weibull, exponential Weibull, Kumaraswamy Weibull, beta Weibull, and the three parameters odd lindly Weibull with three parameters models so the Odd Lindley Weibull model is a good alternative to these models in modeling glass fibres data as well as the Odd Lindley Weibull model is much better than the Weibull, Lindley Weibull transmuted complementary Weibull geometric and beta Weibull models so it is a good alternative to these models in modeling time-to-failure data.

The objective of this paper was to investigate farmers’ knowledge and management of rice blast disease in Tanzania. Farmers’ household survey was conducted in five districts namely Mvomero, Morogoro rural, Ulanga, Korogwe and Muheza in April and May 2017. Data were collected through face-to-face interviews using semi-structured questionnaire and observations made through transect walks across selected villages. Farmers observed symptoms of rice blast disease for the first time in the past 3 to 10 years, with higher severity of blast disease in April to May each year. About 46.3% of the respondents were not aware of the cause and spread of rice blast disease. About 39.9% of the respondents associated rice blast disease with drought, high rainfall and temperature (8.7%) and soil fertility problems (5.1%). About 18.7% of the farmers reported burning of crop residues, 17.0% use of ash, 4.0% use of nitrogen fertilizer and 6.3% application of fungicide for management of rice blast disease. The majority (54.0%) of farmers did not apply any management method. Most farmers planted local upland rice varieties, with only 7.7% using improved varieties. About 69.6% of the respondents shared information on disease management among themselves. Lack of knowledge, ability to afford and unavailability of effective blast disease control methods were reported to affect the management of the disease. Strengthening the capacity of farmers to identify the disease and proper management practices will sustainably solve the problem of rice blast disease in upland rice production.

This study was conducted to determine the effects of black seed oil (0.1% and 0.5%) applications with and without modified atmosphere packaging (MAP), on the postharvest quality of pomegranate cv. ‘Wonderful’. Fruit samples were stored at 6.5±1 oC with 90-95% relative humidity for 150 days and quality analysis done at 30-day intervals. Furthermore, after each storage period, fruits were removed and kept at 20 oC for 7 days to simulate a period of shelf-life. MAP alone or in combination with black seed oil application found to have a significant influence on the maintaining of fruit weight. Percent reduction in the fruit weight 150 days after storage (DAS) was 4.7% and 8.8% for black seed oil (0.5%)+MAP and control+MAP applications, respectively, where it was 18.9% for the control without MAP. The juice content of pomegranate fruits was 31.4% at harvest and it decreased to 21.9% on the control treatment in 150 days. Furthermore, juice content of the fruits with control+MAP and propolis+MAP were determined as 25.8%, and 28.1%, respectively, at 150 DAS. Applications of 0.5% black seed oil especially when combined with MAP, have found to be effective in preventing weight loss, preventing juice content, controlling gray mould development and decelerate the occurrence of chilling injury.

Boron sufficiency supply to plant in calcareous soils of arid regions is severely reduced under arid climatic conditions. Therefore, this study was conducted to determine the effect of Boron (B) fertilization on yield of Wheat grown in calcareous soils of arid regions. Boron was added at two rates namely 0 and 0.5 mg B kg-1 soil to three most common textured class’s soils. Straw and grain yield was determined on oven dried basis. B content of plants was determined as well. Straw and grain yield of wheat was significantly increased by (67.0 and 87.1%), (24.5 and 82%) and (64.5 and 48%) under the addition of 0.5 mg B Kg-1 soil over that of no B addition to clay, loam and sandy loam soil, respectively. Results also showed that wheat grown on the coarse-textured soil had the least B uptake per pot compared to loam and clay textured soils. B content in straw and grain was increased by (77.4 and 121%), (81.2 and 157%) and (184 and 96.9%) under B addition compared to those of zero B addition to clay soil, loam soil and sandy loamy soil, respectively. Response to B addition, significantly, increased in all soils due to increase of available B content in soils which may suggest the importance of adding adequate rate of B application under cropping system of arid regions.

The purpose of this study is to investigate the relationship between repeated sprint performance and velocity values during loaded-squat jump exercise. In accordance with this purpose, 23 kickboxing athletes (age: 21,1 ± 2,10 years; height: 178,7±5,01 cm; weight: 70,8±7,85 kg) participated voluntarily in this study. Participants were performed to repeated sprint test and loaded-squat jump exercise by using an external load corresponding to 40 % of their body weight and velocity parameters were obtained as mean velocity (MV), mean propulsive velocity (MPV) and peak velocity (PV). Descriptive statistics were used in analysis of data. In addition, Spearman Correlation Analysis was used to determine the relationship between repeated sprint performance and velocity values during loaded-squat jump exercise. According to the analysis results; while total running times and fatigue index values in repeated sprint test of subjects were obtained as 52.4 (±1.96 sec) and 4.98 (±2.36%) respectively; velocity values during loaded-squat jump exercise were obtained as 1.38 (±,07 m/s -1 ) for MP, 1.54 (±,10 m/s -1 ) for MPV, and 2.58 (±,15 m/s -1 ) for PV. In addition, it was determined that there was no any statistically significant difference between MP (r= - ,148; r= - ,072, p>0.05, respectively), MPV (r= - ,335; r= - ,150, p>0.05, respectively), PV (r= ,010; r= - ,034, p>0.05 respectively) and total running time and fatigue index values in repeated sprint test. As a result, it can be suggested that velocity values during loaded squat jump exercise have no statistically significant effect on repeated sprint performance.
