Abstract
The first objective of this study is to identify the types of errors made by students in their ESL writing. The second objective is to compare the types of errors (overall, spelling, mechanics, grammar, coherence, sentence structure and lexical) in descriptive writing, according to gender. The third objective is to explore an ESL teacher’s views on how to minimize students’ errors in their ESL descriptive writing. This descriptive study has used the QUAN-qual model whereby the quantitative data was collected using a descriptive writing test while the qualitative data was collected through a face-to-face interview with the ESL teacher. The sample of this study comprised 102 senior one students (47 males and 55 females) from a Chinese private school in Kuala Lumpur. The findings from quantitative data revealed that female students made significantly less errors than male students in their overall writing, spelling, grammar, sentence structures and lexical items. However, the difference in errors between male and female students in the area of mechanics and coherence was not significant. The findings of the qualitative data support the quantitative findings which indicate that students made most errors in the areas of grammar and sentence structures. On how to minimize students’ errors in writing, the teacher opined that giving more exercises in grammar and sentence construction can enhance students’ writing skills. This study therefore has crucial theoretical, pedagogical and practical implications for both ESL students and teachers alike.
Contribution/ Originality
This study is one of very few studies which have investigated error analysis in ESL descriptive writing among Chinese private school students in Malaysia. The findings suggest that ESL teachers should employ appropriate pedagogy to minimize students’ errors in the area of grammar and sentence structures.

Journal: International Journal of Education and Practice

Export to    BibTeX   |   EndNote   |   RIS

Abstract
The topic of play and development has been of immense importance and controversy in early education and child development field throughout the twentieth century and into the present decade. The trend of current early education is to introduce academics sooner for younger students in order for programs to remain competitive and have parents choose more academically based preschools. The trickled down effect of State Standards has also pushed academics into the early childhood classroom more than a decade ago. Hence, reducing or at times leaving out time for active play in the classroom. In some classrooms, play is replaced by passive play led be technological games rather than imaginary play that involves peer interactions. Educators are faced with the challenge of reducing play and the benefits and politics involved in play. This article highlights the concept of play through the lens of Foucault and describes key benefits that can support the academic achievement of students as they continue on to later grades by changing the regimes of truth on play. This research highlights three major developmental aspects of play and their impact on early childhood development. Specifically, language development in Monolinguals and DLLs, self-regulation, and emergent literacy skills.
Contribution/ Originality
This study contributes to the existing literature regarding the importance and lack of play in the early years. This paper provides support and highlights the developmental importance of play as it relates to language/social skills in dual language learners, both cognitive and impulse control, and literacy skills.

Abstract
The rubber which is generated from scrap tyres (tires), identified by crumb or powdered rubber. Day after day, discarded or scrap tyres create huge environmental problems. As long as the scrap tyres are regarded as a non-decade material those disrupt the clean environment. Using this rubber in pavement and asphalt has become a great interest and proposal for researchers for overcome this issue in recent years. Researchers and engineers discovered another way to improve asphalt concrete, by adding crumb rubber (CR) into asphalt concrete. This is done by two methods; first method rubber placed in bitumen and completely or partially reacted with bitumen, this will become binder modifier (wet process). Second method replacing this rubber with fine aggregates which are not dissolved completely with bitumen (dry process). In this study crumb rubber is added into mixture initially by substituting rubber with amount of fine aggregate. Thereafter laboratory tests; penetration, ductility, softening point, elastic recovery and moisture susceptibility test were conducted. These tests were performed, investigated and compared to evaluate the effect of indirect tensile strength (ITS) on asphalt concrete modified with several ranges of crumb rubber. It has been shown that (0%) is control sample, while (2, 4, 6, 8 and 10) are percent of rubber by the total weight of aggregate. One of the critical issues in asphalt pavement is moisture damage. The existence of moisture play a great role in reducing the stiffness of the asphalt mix as well as makes the chance for stripping of the asphalt from the aggregate. This study evaluates the strength loss by comparing two methods of ITS test, which are conditioned (tested in saturated state) and unconditioned (tested in dry state) samples. Marshall Mix method was applied for preparation of total 24 samples for both states of ITS. The results show that for conditioned samples 6% of CR gives the highest value of tensile strength, (892) Kpa. While in unconditioned samples, 10% of CR gives even higher value of strength, compared to conditioned and control sample, (933) Kpa. According to AASHTO T 283-14, the tensile strength ratio (TSR) results of all samples are within the standards, using the minimum value of 80%. For asphalt modified with (2, 4, 6, 8 and 10) % of CR, the TSR values are (95.3, 97.7, 97.4, 93.6 and 90.9) % respectively. Moreover the results are discussed in detail in this study. As summary, the optimal dose of CR is 4% which gives better performance for penetration, softening point, elastic recovery and tensile strength ratio.
Contribution/ Originality
This study contributes in the existing literature, to investigate the binding medium between concrete asphalt with crumb rubbe. This study uses new methodology which is called Wet Process, mixing crumb rubber with asphalt prior to the aggregate. This study originates new formula to improve asphalt and asphalt concrete. This study is one of very few studies which have investigated tensile strength ratio (TSR) by using Indirect Tensile Strength Test, and elastic recovery for conventional mixture.

Journal: International Journal of Geography and Geology

Export to    BibTeX   |   EndNote   |   RIS

Abstract
The study area begins from the eastern part of the Lake Iznik which is in the southeast of Marmara Region in Northwest Turkey, and extends to Mekece. The area is part of the North Anatolian Fault Line, which has been operating since Miocene. Gemlik Gulf-Iznik Depression-Karadin Trough, and Pamuk Plain are the depression series from west to the east which developed due to the fault. During the cool and rainy periods of the Pleistocene, a part of the depression filled with water and became the Lake Iznik. In this period, there have been level changes on the lake due to the climate oscillations and some lacustrine terraces formed. Main geomorphological units in the study area are; high mountain ranges, high and low plateaus, plains and flat fields. Erosion surfaces, which spread widely in the study area, have been handled and evaluated according to Prof. Dr. O?uz Erol’s method. Erosion surfaces were dated as Lower-Middle Miocene surfaces, Upper Miocene surfaces and Pliocene surfaces by applying Erol’s ‘Relation Method Between Slopes and Contour Lines’. Some of these surfaces are valuable for the settlement and agriculture because of the small amount of the slopes. It can be said that the research area has a polycyclic feature, and it is in the late youth stage of geomorphologic development.
Contribution/ Originality
This paper which is based on the author’s PhD thesis titled “The geomorphology of the land between Iznik-Mekece” describes erosion surfaces of the region according to Prof. Dr. O?uz Erol’s ‘Relation Method between Slopes and Contour Lines’.

Abstract
Two varieties of OFSP (Ex-Igbariam and Umuspo 3) planted at 20 cm x 1m, 30 cm x 1m and 40 cm x 1m and harvested after 12th and 16th weeks were analyzed for nutrient compositions. The statistical analysis showed wide variations in their proximate, mineral, vitamin and chemical contents. Moisture and protein contents were higher in 12th week of harvest than at 16th week irrespective of planting distance. Ash, fat, fibre and carbohydrate contents were higher at 16th week of harvest irrespective of the planting distance. Specifically, Umuspo 3 was higher in moisture and fat values while Ex-Igbariam was higher in ash, fibre, protein and carbohydrate. Calcium and vitamin C were higher at 12th week of harvest, while magnesium, potassium and vitamin B6 were higher at 16th week of harvest. Specifically, vitamin B6, phosphorus, magnesium and calcium were higher in some Ex-Igbariam lines especially in V4S3 than in Umuspo 3 lines. The chemical results showed that alpha amylase was higher in Ex-Igbariam V4S2 at 16th week of harvest while reducing sugar was higher in Umuspo 3 V1S1at 12th week of harvest. Total carbohydrate was higher in Umuspo 3 V1S1at 12th and 16th weeks of harvest. The general results indicates that the proximate, minerals, vitamin and chemical compositions of most of the variety lines were richer at 16th than at 12th week of harvest irrespective of planting distance. While 40 cm planting distance in V4S3 (Ex-Igbariam) gave higher yield of proximate, mineral, vitamin and chemical parameters, Umuspo 3 did not maintain a particular trend. Ex-Igbariam variety showed higher nutrient values than Umuspo 3 and may be recommended as a nutrient dense sweet potato staple for better nutrition.
Contribution/ Originality
This study contributes in the existing literature of the effect of farming practice: planting distance and harvesting time on nutrient composition of OFSP cultivars (Umuspo 3 and Ex-Igbariam) grown in Nigeria. Results showed that Ex-Igbariam was the best OFSP cultivar with dense nutrient content. This research finding can be used to advocate for increased OFSP utilization in Nigeria.

Abstract
English teaching mainly covers five interdependent and interrelated basic language skills of listening, speaking, reading, writing and translating. English writing is considered an important part in English output stage, which is often an ultimate goal of language learning. However, the current English writing teaching in China is not so satisfactory, and a disadvantage exists in Chinese traditional approach of writing-focused instruction: Students’ writings often fail to achieve the aim of effective information expression and communication. Cultural linguists, social linguists and cognitive linguists believe that there is an inseparable relationship between language and culture, so cultural connotation of language cannot be ignored in the English writing teaching in order to realize the precise use of language. The paper is attempted to discuss the cultivation of cultural consciousness in the English writing teaching in terms of vocabulary, syntax, and text under the structure of linguistics so as to improve teaching efficiency of Chinese English writing in some sense.
Contribution/ Originality
This study documents the ways of cultural consciousness cultivation in English writing teaching under the guidance of linguistics.

Abstract
The purpose of the study was to investigate the extent of community members’ involvement in school activities to enhance teacher attendance in the East Mamprusi District of Northern Ghana. The research design was a survey. Stratified sampling method was employed to group the study population into five (5) strata of teaching staff, SMC/PTA executive members, District Education Officers, and community members. Questionnaires were used to collect data from 150 participants. The Statistical Product for Service Solution (SPSS) version 20.0 was used to analyze the data collected. The purpose of the study was made known to participants. The findings depicted that though the level of community involvement in the activities of the schools was encouraging it had limited influence on teacher attendance. Characteristics such as age, gender, ethnicity, language, wealth, weak democracy, illiteracy, work and time served as barriers to community involvement in monitoring teacher attendance. Recommendations of the study include, the training or sensitization of SMC and PTA executives as well as community members on their rights and privileges to be involved in school activities, especially monitoring of teachers’ attendance. In addition, they should be equipped with skills and knowledge to exercise their duties and responsibilities. The study will benefit all stakeholders of education and policy makers.

Abstract
The purpose of this study is to examine the profitability of Momentum based- trading strategies and investigate the causes of such profitability in Damascus Securities Exchange (DSE) market. The study analyzed 16 Momentum strategies based on full rebalancing and equally weighted techniques using monthly data from January 2010 to December 2016. The findings of the study showed low but significant Momentum effect, where the returns of Momentum portfolios were statistically positive only in 1 out of 16 strategies. Our findings suggest that Momentum strategy is applicable for winner portfolios whereas contrarian strategy is more appropriate for loser portfolios. We also adopted Market Model in order to investigate the possible risk-based explanations of Momentum profits, but we found that market risk is unable to explain the Momentum profitability in DSE market.
Contribution/ Originality
This study contributes in the literature related to financial market efficiency by finding the link between Momentum strategies and abnormal returns. Consequently, providing an evidence about the link between Momentum effect and market efficiency in emerging markets.

Abstract
In the wake of increased investment in and new policies regarding Residential Solid Waste Management (RSWM) in Lagos state and the attendant consequence of inefficiencies currently observed with the system, this study describe the state and determinants of waste management services in rural Lagos State. A well-structured questionnaire, which consist of two sections, was used to elicit demographic and residential solid waste collection information from 200 household heads sampled using the multi-stage sampling in 3 Local Council Development Areas (LCDAs). Data were analysed using both descriptive and Dprobit, an advanced probit logistic model. Results show that the mean and standard deviation for whether a ward/neighborhood has RSW collector was 0.23 and 0.42. Similarly, mean and standard deviation for Private Sector Participation (PSP) operator employing RSWC workers was 0.22 and 0.41. Among demographic and residential solid waste collection characteristics, income, population, PSP charges or rates and distance to dump site are found to be determinants of RSWC services in rural areas of Lagos state. The analysis shows that a one thousand increase in Mean income would increase the possibility of providing waste Transportation services by 0.20 percent and the possibility of employing waste workers by only 0.17 percent. Conversely, a one Kilometre increase in distance to dumpsite would reduce the possibility of PSP operator acquiring a compactor. Government incentivisation of rural residential solid waste collection would go a long way to eliminate poor RSWC in rural areas of Lagos State.

Journal: The International Journal of Biotechnology

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Some grains were analysed for their nutrient compositions for use in the formulation of bacteriological media in consideration of cheap and effective alternative to the conventional media. The media were respectively formulated using Acha (Digitaria exilis), Maize (Zea mays), Rice (Oryza sativa), Guinea corn (Sorghum species) and Millet (Pennisetum glaucum). Proximate analyses of the grains showed reasonable amounts of carbohydrates (55.0 to 73.9%), moisture contents (9.92 to 11.25%) and crude proteins (7.39 to 11.77%). Crude fibre and ash had the least % in the five grains used. Amongst the macro-elements, carbon is the most abundant followed by nitrogen. Using atomic absorption spectrophotometer (AAS), Zn, Co, Cu and Mo were not detectable in the grains, whereas Mn was present in minute quantities (? 0.015%). All the bacteria assessed grew on the formulated media. Statistical analysis of the data indicated homogeneity in growth rates of the test bacteria on most of the media formulated. However higher microbial counts observed on millet extract agar (MIEA) suggests that the medium could serve as an alternative growth medium for bacteria in place of the conventional nutrient agar (NA) with reduced cost.
Contribution/ Originality
This study is one of the very few studies which have investigated nutrient compositions of different grains for use in the formulation of bacteriological media.

Abstract
An experiment was conducted to determine the effect of treated palm kernel meal in diets on production parameters of Nile tilapia Oreochromis niloticus reared in concrete tanks. Fingerlings of Tilapia with an average initial weight 6.22 ± 0.25 g and an average size 7.58 ± 0.21 cm were fed four isonitrogenous diets each containing 30% palm kernel meal treated one-hour or not. So we have NT (untreated), DW (dipped in water), CW (cooked in water) and SW (steamed). These diets were compared with a commercial fish feed, Raanan (RA), all about 32% crude protein. After 8 weeks of experiment the final body weight varied between 29.57 and 43.01 g according to the tested treatments. The best growth rate and food conversion ratio were obtained with diet CW containing palm kernel meal cooked in water with specific growth rate (SGR) of 3.24 %/d and food conversion ratio (FCR) of 1.97 against a SGR of 3.44%/d and a FCR of 1.72 obtained with commercial feed (RA). Moreover, the tested diets do not seem to have any effect on the intestine size but the cooking seems to act on fish liver weight and body composition. The production parameters were improved with the diet containing palm kernel meal cooked in water which seems to be the interest food for O. niloticus on growing.
Contribution/ Originality
The authors declare that there is no conflict of interests in relation to this original article. This study is one of very few studies which have investigated on palm kernel meal in diet in order to reduce the cost of fish feed.

Abstract
Since its insertion in 1998, Kigali Institute of Education, currently known as College of Education under the University of Rwanda, henceforth ‘The University of Rwanda-College of Education (UR-CE)’, it`s first mission has been training and producing teachers for secondary schools in Rwanda. To a certain extent, bearing in mind that Rwanda Education Board (REB), an institution in charge of education in Rwanda from kindergarten to secondary education, in designing its programmes, UR-CE curricula from Rwanda Education Board (REB) were taken into account. Recently, REB has introduced a new Competence-Based Curriculum (CBC) replacing the knowledge-based one that has been in practice for many years. Hence, the UR-CE is also obliged to revise its programmes and align them with the new CBC designed for secondary schools so that the UR-CE graduates are equipped with required knowledge and practical skills to cope with the demands of the newly introduced secondary school competence-based curriculum. Relying on existing documentation supported with our observations and critical analysis, this analytical paper attempts to highlight some of the knowledge, skills and attitudes deemed important to be incorporated in new UR-CE revised programmes in a way to align them with the secondary school Competence-based curriculum designed by REB. It also seeks to point out some of the challenges that might be associated with the teaching of such suggested knowledge, skills and attitudes; and provide measures to mitigate such challenges.
Contribution/ Originality
This paper`s primary contribution is highlighting the gaps in the UR-CE existing programs, how to adjust those programs and align them with the current competence-based curriculum designed for secondary schools in Rwanda. It describes aspects, skills and skills to incorporate in the new programs taking into account the CBC requirements.

Abstract
Despite their imperative role in water resources management, distributed hydrological models like SWAT require calibration that can be challenging due to uncertainties of parameters involved. Prior to modelling of hydrological processes, these parameters and their uncertainty range need to be identified. The objective of this study was to conduct uncertainty analysis of hydrological processes and to calibrate the Soil and Water Assessment Tool (SWAT) for stream flow and sediment yield modelling in Thika River catchment. Sequential Uncertainty Fitting program (SUFI-2) was used to conduct sensitivity and uncertainty analysis. Stream flow was calibrated and validated between the years 1998 to 2013 for gauging stations 4CB05 and 4CB04. Manual sediments calibration was achieved by constraining the MUSLE parameters using the bathymetric survey data. Two uncertainty indices, p and r factor, were obtained as 0.72 and 0.65, 0.65 and 0.45 during calibration and validation, respectively. Statistical performance indicators showed a good match between the observed and simulated values which indicated that the model was well calibrated for simulation of stream flow and sediments yield in the catchment.
Contribution/ Originality
This study contributes in the existing literature on the estimation of base scenarios using sequential uncertainty fitting algorithm. The study outlines the analysis of parameter uncertainties and calibration for estimating impacts of conservation methods on stream flow and sediment yield.

Abstract
Extract of Elephant Foot Yam (EFY) is known to contain flavonoid that is an antioxidant compound and thus has the potential to be utilized as functional food in the form of beverages. Functional drinks made from plants are usually presented as healthy drinks, which in this case is in the form of syrup. This study aims to determine the antioxidant activity, pH value, viscosity and sensory properties of EFY extract syrup with different extract formulas and find out which of the formulated syrup produced is best based on its antioxidant activity and physical characteristics. The syrups produced were derived from 3 different types of formulas determined which were F1 (0.6% extract), F2 (2% extract) and F3 (4% extract). The parameters observed in this study were antioxidant activity, pH value, viscosity, and sensory properties of the syrup. The results obtained show that variations of the extract concentration in the formula have effects on the antioxidant activity, pH value, viscosity, aroma, and consumers’ preference of the syrup. The syrup formula with a concentration of 4% extract (F3) was found to have favorable properties as it has the highest antioxidant activity of 71.39 ppm; pH value of 4.97; and viscosity 0.265 c. In terms of consumer’s preference, the syrup with 0.6% extract (F1) is most preferably in color, flavor, and aroma. Thus EFY potentially as antioxidant source that can be added into the healthy drink in the form of syrup.
Contribution/ Originality
This study is one of very few studies that have investigated the potency of a tropical tuber grown primarily in Southeast Asia namely Elephant Foot Yam (EFY) as a functional baverage in the form of syrup preparation.

Abstract
One fundamental way of ensuring success in workplaces is to set the goal to be actualized. Education industry is not an exception. This study evaluated the goals of art education programme in the unity schools of the North eastern zone of Nigeria. Three out of the six states in that zone were selected. The research design is survey. The target population is the entire teachers and students of the art education programme in Federal Unity Schools. Four hundred and ten constituted the elements in the population; in which case, there were twenty art teachers and three hundred and ninety were students. A sample size of two hundred and seventy-six was taken from both the art teachers and the Senior Secondary students using the purposive sampling technique. Two objectives and two research questions were set to guide the study. Statistical tool in the like of percentage and Table of frequency distribution were used for data analysis and presentation. Findings show that though Art Education goals are achieved, poor performance, inadequacy of infrastructural facilities and instructional materials were also observed.
Contribution/ Originality
The study reveals the current state of art education programme in North-eastern Nigeria and gave insight to the significance of its goals to the mental development of learners in that zone. The study has also served as an impetus for creating students’ and parents’ interest in art education.

Abstract
This paper analyzes the potential of gamified tests as a replacement for conventional tests, and the benefits and challenges of the application of gamification in universities and colleges. It looks into the pros and cons of the use of gamification in higher education, reviews the application of gaming elements in assessments and suggests that the incorporation of gamified activities in some of the practical tasks in the classroom helps to develop and nurture the students’ practical competences. The article concludes that although the potential of gamified assessment cannot be ignored, the idea that gamification can result in the mastering of the theoretical concepts has not been proven.
Contribution/ Originality
This study contributes in the existing literature on the application of serious games in the context of higher education by focusing on assessment. It is one of very few studies which looks into the possibility of replacing traditional assessment tools with game-based tests.

Abstract
Topographic maps are used to determine erosional landform origins along the Little Missouri River-Powder River drainage divide in the Chalk Buttes areas of Carter County, Montana. Asymmetric drainage divides, drainage divide gaps, and isolated erosional remnants are used to determine a sequence of erosion events beginning with headward erosion of northeast-oriented Little Missouri River tributary valleys and ending with headward erosion of the deeper north-northeast and north-northwest oriented Powder River valley. Gaps notched into present day drainage divides and orientations of valley heads on either side of those gaps suggest many closely spaced southeast-oriented streams flowed across the region immediately prior to being captured by headward erosion of deeper north-oriented valleys. Buttes capped by horizontal Miocene Arikaree sandstones stand 500 feet (152 meters) or more above surrounding Little Missouri River tributary drainage basin elevations while the Powder River valley floor elevation is as much as 800 feet (244 meters) below those surrounding elevations. A water source could not be determined from the map evidence, however the study area is located to the south and west of a known continental ice sheet margin and large southeast-oriented ice-marginal melt water floods should have logically crossed the region.
Contribution/ Originality
This study documents how large volumes of southeast-oriented water of probable continental ice sheet melt water origin deeply eroded the Chalk Buttes area of Carter County in southeast Montana and suggests that at least one continental ice sheet deeply eroded the North American continent.
