The primary purpose of this study was to obtain empirical evidence and provide a methodological alternative for helping understand how simulation serves to learning. Well-structured system design and unstructured learning implementation bring complexity to dealing with learning in total enterprise simulation, specially, how to investigate learning emanated from the simulation game’s structure and decision-making requirements has studied very few. Due to the multiple aspects of individual learning situation and the inevitable structural design differences in simulations, student authored reports were used as data source to analyze the connections of learning-performance based on means-ends theory and the model was constructed with the components, namely Attributes, Consequences, and Values. With limitations of research, the study provides practical evidence and student insight into logic and structure of the simulated firm experienced, as well as demonstrates the use of means-ends approach for research on the issue of simulation-based learning and performance. Contribution/ Originality
The paper contributes the first means-ends analysis of the connections of in-class simulation-based learning-performance by using the learning setting and participant-authored reports. Contrasted with previous studies which were essentially oriented in product/service decision-making, this study was built on the efforts to enhance the understanding of how the virtual management practices contribute to generation of personal values, rather than to focus on simulation system’s external validity.

Analysis of the Factors Affecting Changes in Land Cover Patterns in Rural Districts in East of Guilan Province (Iran) for Foresight
Foresight is among the key topics in natural resource protection for sustainability of rural settlement system. In foresight of land cover evolutions, identification of factors affecting the evolutions is of paramount importance. In the present research, in order to undertake foresight and sustainable land planning in rural districts in East of Guilan as a special ecologic zone encompassing 744 villages, principle variables were collected via a questionnaire using Delphi method with the help pf experts, followed by calculation of significance factors. A total of 93 variables were found to affect the changes in land cover within the study area at local, regional and national scales. Among these, key variables were identified utilizing MIC-MAC Software. In order to develop scenarios by a 20-member expert panel, 19 key drivers of the changes in land cover were homogenized and 9 primary descriptor were defined. For each descriptor, three variant qualitative component were prepared, which described all possible cases from the most critical case to the most desired one. In the next stage, with the help of cross-impact balance matrix and Monte Carlo simulations in Scenario Wizard Software, a total of three scenarios with 15-year horizons were obtained based on maximum consistency. Finally, based on the maximal effectiveness on protection of natural land cover and continuation of sustainability, the obtained scenarios were designated as balanced ecologic changes, relatively balanced ecologic changes, and imbalanced ecologic changes.

21st Century has marked high velocity of data generation not only in terms of size but also in variety. Analyzing large data sets with different forms is also a challenging task. Data Mining is regarded as efficient method to extract meaningful information as per user requirements. But considering the size of modern data, traditional data mining techniques are failing. Clustering can be regarded as one of the most important technique to mine the data by splitting large data sets into clusters. The paper’s primary contribution is to provide comprehensive analysis of Big Data Clustering algorithms on basis of: Partitioning, Hierarchical, Density, Grid and Model. In addition to this, performance comparison of algorithms is performed on basis of volume, variety and velocity. Contribution/ Originality
Culture is not a new concept within the social sciences. In fact, culture has been widely discussed for years to investigate how it has evolved and how it still affects human communication. The aim of this article is to introduce the concept of culture and illustrate its relevance in key theoretical discussions and debates in the social sciences. Also, it aims based on secondary research evidence to highlight how differing cultural factors affect learning and assessing in higher education. The paper concludes that it is essential for assessors to consider the unique cultural characteristics when assessing their students’ performance. Contribution/ Originality
This study contributes in the existing literature on the role of culture in education by focusing on assessment. It is one of very few studies which suggests that assessing students’ performance should not take place independent of cultural particularities and sets the ground for designing alternative, culturally responsive assessment tools.

Research Article
Author(s):
Journal: Current Research in Agricultural Sciences
This study was undertaken to evaluate the physical and chemical properties of three contrasting soils under four land use systems. The soil types considered were Vertic Cambisol, Haplic Lixisol and Ferric Luvisol while the land use types studied are cocoa plantation (CP), grazing land (GL), fallow land (FL) and cultivated land (CL). Soil samples were collected at 0-15cm and 15-30cm depths respectively from each of the locations. The soil samples were air dried and passed through a 2mm sieve and taken to the laboratory for analysis. The result of the study showed a higher sand content being recorded in Haplic Lixisol (CL) and Ferric Luvisol 2 (FL) followed by that of Vertic Cambisol (CP) and Ferric Luvisol 1 (GL) in the upper 0 to15 cm depth and lower 15-30 cm. The soil pH within the soil types and depths could be categorized as slightly acidic to moderately alkaline. The organic carbon content of the soils was generally low; it varied from 0.18% to 1.29 % for 0 to 15 cm depth with Vertic Cambisol (CP) having the highest value. The mean available P content was not significantly (P?0.05) different among the soil and land use types. The total nitrogen recorded was generally low 1.006 - 1.304% at 0-15cm while at the lower depth it ranged between 0.566 – 0.768%. The exchangeable bases also decreased following cultivation. The result of the study shows that continuous cultivation without adequate management practices causes a decline in the physical and chemical properties of the soil. Contribution/ Originality
This paper contributes to existing literature that agriculture being the main user of land is constantly being affected by land use changes. It further seeks to assess how the physical and chemical properties of the different soil types are being affected by different land use types.

Research Article
Author(s):
Journal: International Journal of Education and Practice
The entrepreneurial skills have been regarded as the vital factor for the business sustainability. The previous study confirmed that there was a gap for entrepreneurial skills between several countries. The factor driven countries (such as Indonesia, Philippines, Vietnam, etc.) are dominated with the wholesale/retail activities, while the innovation driven countries (such as Sweden, Belgium, Norway, etc.) will be more dominated with ICT/Finance or the professional services activities. The wholesale/retail activity is said to be easier to enter since it’s generally require lower skill levels. Entrepreneurship education (EE) is needed to enhance the development of the entrepreneurs in order to fulfill this gap, so it is necessary to evaluate the EE program delivered by the university in shaping the entrepreneurial competencies. This research did an evaluation towards the entrepreneurship education program by identifying the learning process (including the definition and objectives of EE, the course contents, the teaching methods, and community outreach activities), and measuring the impacts (by using entrepreneurial competencies). This research was done in the Management of Business in Telecommunications and Informatics, Faculty of Economics and Business in Telkom University. The result is aimed to improve the learning process within institution. On the other side, this research is expected to help the university to achieve the target to be a Global Entrepreneurial University in 2038, particularly to create the global entrepreneurial graduates. This study is also expected to improve the economic growth by increasing the university’s role in creating the graduate entrepreneurs. Contribution/ Originality

Making Schools More Girl Friendly: Exploring the Effects of Girl Friendly Space on School Attendance of Adolescent Girls
Research Article
Author(s):
Journal: International Journal of Education and Practice
School enrolment and attendance for adolescent girls is a key priority for education sector in most developing countries. In Somalia, this is even more prominent given the low enrolment rate of girls and the gender specific challenges that the girls face. Girls in Somalia often remain absent from schools during their menstrual periods due to lack of hygiene facilities and the social stigma in using the facility where they exist. Girl Friendly Space (GFS) has been adopted as a means to mitigate these challenges. Despite strong narratives of the effectiveness of the GFS, there is lack of evidence on the impact of GFS on reducing school absenteeism. By using secondary data, this study explores the potential effects of GFS on reducing school absenteeism. The study indicate that having GFS in schools can reduce the likelihood of adolescent girls being absent from school in the past month by about 15 percentage points. Absenteeism due to ‘sickness’ is about 17 percentage points lower in schools with GFS compared to schools without the facility. Although this study cannot fully address the selection bias to claim these as impact estimates, the differences for boys between the two types of schools in absenteeism is much lower indicating possible effects of GFS on girls’ school attendance. Contribution/ Originality
This study is one of very few studies that have sought to demonstrate potential effects of girl friendly spaces in reducing adolescent girls’ school absenteeism in culturally sensitive regions like Somalia. Primarily the study shows equipping and enhancing privacy in girls-only toilets can potentially reduce absenteeism up to 15 percentage points.

Palm Kernel Separation Efficiency and Kernel Quality from Different Methods Used in Some Communities in Rivers State, Nigeria
The separation efficiency and palm kernel quality of five palm kernel shell separation methods used in selected communities in Rivers State, Nigeria were evaluated. The methods include traditional handpicking, clay-water bath (kaolin), mechanical dry separation, pneumatic and hydrocyclone separations. The weight of recovered palm kernels obtained from each separation method was determined and used in the calculation of separation efficiencies. Free fatty acid (FFA), shell/fibre and moisture content of the palm kernels recovered from each separation method was determined. The results show that the least free fatty acid (FFA) content of (3%) was found in sample separated by the pneumatic method and highest (8%) in the clay-water bath (kaolin) method. High moisture content of 11% was recorded for kernels separated by clay-water bath (kaolin). Pneumatic separation method retained the least percentage of shell/fibre content (2%). Hand picking and clay-water bath (kaolin) methods had shell/fibre retention of 8% and 6%, respectively. However, mechanical, pneumatic and hydrocyclone separation techniques conform to the quality parameters when compared to SON/NIS standard. The mechanical, pneumatic and hydrocyclone separation methods gave higher separation efficiencies of 74, 90 and 96% respectively and palm kernels of superior quality that meets the palm kernel industrial standards. There was no significant difference (P>0.05) in separation efficiencies between the traditional hand picking and the clay water bath methods however there was a significant difference (P<0.05) between the above two methods and mechanical, pneumatic and hydrocyclone separation methods. Contribution/ Originality
This study shows that pneumatic and hydrocyclone separation methods are the most efficient in separating cracked palm kernel mixtures. This study also provide information on the best method of palm kernel recovery that meets quality requirement for Nigerian Industrial standard.

Childhood Adversity, Families, Neighborhoods, and Cognitive Outcomes: Testing Structural Models of the Bioecological Framework
Research Article
Author(s):
Journal: International Journal of Education and Practice
Over half of the children in the U.S. experience adversity early in childhood. These experiences, along with conditions in their families and neighborhoods, have profound developmental effects. The bioecological model of development includes these proximal contexts in a theory of development that incorporates the threats and supports present in these spaces to describe child development. This study used structural equation modeling to build latent measures of childhood adversity, family conflict, and neighborhood quality and tested theoretically-implied pathways to determine the relationships among these measures and cognitive outcomes in children. This study of US children ages 5-17 (N = 2,907) employed a nationally representative sample from the Panel Study of Income Dynamics to create and test these measures. Results indicate that adversity, family conflict, and a lack of neighborhood quality negatively impact cognitive function, even when controls for socioeconomic status and race are introduced. Testing of models indicated that family conflict and neighborhood quality are mediated by adverse childhood experiences, and these contexts should not be related to cognitive outcomes without the inclusion of adversity measures. This study provides further insight into the relationships among these contexts and children’s lives, and offers guidance for future research with these constructs. Contribution/ Originality
This study contributes to the literature on Adverse Childhood Experiences and the Bioecological model of development by identifying the mediational nature of family conflict and neighborhood quality measures when relating ACEs to young adolescent outcomes. Additionally, the paper identifies and analyzes latent measures of these variables. Arts and Education » International Journal of Education and Practice » Month: 12-2017 Issue: 12

Journal: International Journal of Education and Practice
Online training permits or encourages a change in the teacher’s role. It is in this sense that the objective of this paper was to analyze the implications of the application of an unconventional model to the teaching process, supported by Information and Communications Technology (ICT) and incorporating new methodological paradigms into the teaching-learning process for course presentation and management, encouraging students to change the role they have played to date, given their preliminary training process, which has been based, nearly always, on a traditional model. Using online courses to support the student-centered teaching-learning process involves knowing what features the online teacher must have and how teachers can help their students in their new role. On the other hand, it is important to employ the lessons learned by traditionalist teachers, because the latter can take advantage of their experience to teach in a better way by implementing the use of information and communications technologies. Contribution/ Originality
This study contributes in the existing literature a learner-orient environment for the teachers and students.in which it is attempted to recognize the importance that the teacher has in this current knowledge society, where undoubtedly the tutor has two decisive roles: offer feedback and manage and strengthen relationships between students-teachers. This study documents aspects such as communicating effectively and the Role of teacher as a central factor in the virtual learning environments Arts and Education » International Journal of Education and Practice » Month: 12-2017 Issue: 12

The Quality of Fried Chips Varies with Cassava (Manihot Esculenta Crantz) Varieties and Soaking Regime
Fried cassava chips are largely accepted in Cameroon but their quality is not consistent. This study investigated the appropriate cassava varieties and soaking regime for processing good quality fried cassava chips. Fried chips were processed from four cassava varieties (0110, 8034, 92/0326, makumba) using four soaking regimes which were: unpeeled roots, soaked for 72 h, peeled roots, soaked for 24 h, peeled roots, soaked for 14 h and peeled sliced roots, soaked for 24 h. The proximate composition, physical characteristic and sensory test were done to evaluate the quality of fried chips obtained. Fried chips processed from variety 0110 presented the highest carbohydrate (77.94±0.34 %) and the lowest moisture (1.75±0.22 %) and fat content (15.11±0.30 %). The variety 8034 showed higher level of Ca, K, and Fe than other varieties. Variety 0110 was more salty, crispy and crumbly with higher global quality. Fried cassava chips processed from peeled soaked roots for 24 h scored the highest global quality as compared to other soaking regimes. Therefore, cassava varieties and soaking regimes influence the quality of fried chips. Socio-economic studies are warranted before large-scale dissemination of results to users. Contribution/ Originality
This study is one of very few studies which have investigated the variation of the quality of fried chips with respect to different cassava varieties. Agricultural Sciences » Journal of Food Technology Research » Month: 06-2018 Issue: 1
