Authors: Notash Masoud Yaghoubi , Shahrebabaki Mas`oud Mahmoodi 
Published: August 2018

E-learning has lately grown into a proliferating area because of its good potentials for instructional and assessment purposes. Context of instruction where e-learning is commissioned can bear implications for the scope and instances of application.Â The present study addresses the major challenges faced in this respect by Iranian practitioners and also offer some practical solutions to these challenges. As a descriptive study in nature, the data population comprised 350 Iranian citizens from various social, economical and educational backgrounds aged between 16 and 53 who were asked to prioritize six major challenges Iranian people face regarding the e-learning arena on a standardized Likert-type scale. The challenges were selected from among those earlier cited in the related literature. Six major challenges to be prioritized were: lack of government support, lack of public awareness, high costs of e-learning, collectivist society of Iran, low-speed internet, internal filtering and external sanctions. The results indicated that lack of public awareness, lack of government support and collectivist society of Iran were chosen by the participants as the main hurdles in the path of e-learning development in Iran, respectively. Further solutions and implications of the study are discussed in the study.
Social professionals in school: a comparative study
Authors: Vieira Ana 
Published: August 2018

School education is progressively becoming a social question and not only a matter of pedagogic nature. The increase of the diversity of the audience present in the school has brought forth policies and differentiating school responses which aim to build a â€œschool for allâ€. In this paper we seek to understand how the growing social tensions which are observed in the form of indiscipline at school are managed, whether towards other social professionals or only towards teachers. This paper presents a comparative study between three educational contexts which comprise socio-pedagogic mediation practices: Educational Context of Early Intervention (TerritÃ³rio Educativo de IntervenÃ§Ã£o PrioritÃ¡ria - TEIP) and two Support Offices for Students and their Families (Gabinetes de Apoio ao Aluno e Ã FamÃ­lia - GAAF). In the three cases, there are senior social workers (tÃ©cnicos superiores de trabalho social - TSTS), social educators, youth workers and social assistants who work with teachers on a daily basis. The research done in this paper focuses mainly on the teachersâ€™ opinion concerning the emergence of these new professions and their socio-pedagogic contribution in the school.

The increased demand for energy, climate change, and energy security concerns has driven the research interest for the development of alternative fuel from plant origin. Biodiesel derived from plant oils, which include edible and non-edible oil have gained interest for the last two decades as alternative for diesel around the world. The purpose of this study was to determine the perceptions of high school students in Jakarta on the regarding renewable biodiesel. The study conducted a survey among twelve-grade. High school students studying in private schools in easten Jakarta Â in order toexplore their perceptions of biodiesel Â production from non eedible oil and edible oil Â for heat and power. A total of 20 item questionnaires were administeredto a total ofÂ 185 students in twelve grades. In addition, three open-endedquestions were asked of the students in order to determine their level of knowledge regarding biodiesel, and power stations. The study data were analyzed using the SPSS statistical package program. The study results revealed that, thestudents were of the perception Â that biodiesel Â use wouldreduce global warming, and that renewable energy sources areenvironment-friendly, non toxic and renewable.In addition, thestudents generally knew about biodiesel Â sources and their importance, although they lacked knowledge about certain aspects of biodiesel.The study recommends energy and educational policy makers to increase awareness of Â non edible and edible oil baseed bioenergy production among young students. In this respect, schools, parents, and media can also play an important role to engage young students in bioenergy related discussions.

Published: August 2018

The sweeping trend of communication technologies increasingly makes computers and computer-based operations an indispensable part of our everyday lives. Education as a institution deeply rooted within the context of the broader community can, therefore, hardly afford to do without the digital era. Assessment, as a subcategory of education, is expected to be under the influence of the same trend. The present study, focusing on the EFL situation in Iran compared two equal-sized advanced learnersâ€™ Â each containing 20) writing accuracy and length. One group employed the traditional paper-and-pencil Â PPT) mode while the other used computer-assisted language testing Â CALT). Â Results indicated a significantly more accurate writing for the CALT group, while a longer writing production for the PPT group. Implications of the study are discussed.

Authors: Ricart Casadevall Sandra 
Published: August 2018

Interest in obtaining a more accurate snapshot of the territory is increasingly relevant in most geographic studies. This proposal is based on the stakeholder analysis approach and the governance model approach to analysing any topic with a geographical profile or interest from an educational and methodological point of view. The selection of those approaches and the application of some related techniques have been used to generate a new tool for identifying and characterizing the key stakeholders in order to understand their behaviour and its influence or power on decision-making processes.Â This methodology can be used by educational members and geographers as a working basis to analyse an exchange social-learning from confronted interests.
POLITICS AND LEADERSHIP FATIGUE IN AFRICA. A THEORETICAL APPRAISAL.
Authors: Akani Christian 
Published: August 2018

Colonialism cannot be forgotten in Africa because of the disorientation and dissonance it enforced. This scenario paved wayÂ for unbridled expropriationÂ of human and material resources. But, by the beginning of the 1940s AfricanÂ nationalistsÂ rejected the colonial political economy, andÂ demanded for self governance.Â The aftermath of their demand engendered a wind of change which swept most African states to statehood in the 1960s. Regrettably, five decades after independence, the continent is still experiencing a free fallÂ in all human development sectors. Those who inherited political power, rather than ensuring inclusive governance have imposed pain and terror on their people . With an analytical , method the paper argues that politics is squarely responsible for the leadership fatigue in the continent. It concludes that for Africa to have the right leaders they desire, the political institutions must guarantee popular participation.

Published: August 2018

Computer simulation is an experiment using a computer model to represent a unique system.Â Variables are defined and parameters to be study are monitored and recorded. Growing caÂ­pabilities and decreasing costs of microcomputers are placing this powerful tool at the fingertips of scientists and engineers. In the past, the use of digital computers in simulation required a considerable amount of programming effort. This is no longer a true statement.Â Simulation provides the student with a greater breadth and depth of information on which decisions could be made. It is also considered one of the most valuable and flexible decision making tools available. Flexible simulation and animation models developed using a multitude of softwareâ€™s available in the market today is considered a very powerful and effective approach in engineering education. Simulation and animation models could easily be used to solve complex and dynamic problems in both the classroom and real life.Computer simulation techniques and soft wares have been used for more than a decade to help engineers in development, trouble shooting, problem solving, and decision making process. The new paradigm in computer simulation is the use of animation and virtual reality to build engineering models and animation, simulate operations and performance. The fantastic progress in computer hardware and software industry has now opened a new and higher level of teaching computer simulation.

Published: August 2018

Different landfills in Jenin district were selected in this research, and are considered the main garbage destination for the north part of the West bank. Due to their expected drastic effect on agriculture, the experiment was carried out to study the impact of such landfills on nearby olive orchards. The results showed that the landfills since their establishment caused drastic reduction of olive production from an average of 1500 kg/hectare in 2005 to 560 kg/hectare in 2009. Furthermore, olive production in the studied area stopped absolutely in 2011 due to complete olive orchard failure. On the other hand, the effect of landfills was studied on vegetables under lab conditions. Therefore, different dilutions of the landfill leachate were used to irrigate tomato and pepper plants. The results showed that leachate caused plant stunting and reduction in leaf surface area when compared with control regardless of dilution used, but more pronounced in dilution zero. On the other hand, chlorophyll concentration was more in plant treated with zero dilution of leachate when compared with other treatments. Number of dropped leaves was more in plant treated with zero dilution of leachate when compared with other dilutions and control. The plants treated with zero dilution died before others treatments. Conclusion: leachate may have a drastic effect on nearby cultivated plant and could affect plant growth and lead to premature plant death.

Published: August 2018

Â Â Â One of the effects of reducing water content on soil is reduction of growth and development of seedlings and variation of field development. Seed priming technique has been known as a challenge to improve germination and seedling emergence under different environmental stresses. The objectives of this research were to evaluate the effects of osmo-priming on germination characteristics and changes of proline, protein and catalase activity of Ocimum basilicum seeds. Results showed that drought stress reduced the germination characteristics and drought stress in -8 bar was the critical stress.Â Priming treatments were include KNO3, PEG and NaCl by 0, -4 and -8 bar concentrations. The seeds were primed with those materials for 8 and 16 hours. The highest germination characteristics were obtained from nitrate potassium in -8 bar for 16 hours priming. Therefore the best seed treatment under drought stress during germination was obtained from the osmo-primed with -8 bar nitrate potassium for 16 hours. The drought stress increased proline and catalase activity but reduced total protein. Priming treatment increases proline, total protein and catalase activity under drought and control conditions. It is concluded that priming results in improvement in germination components of Ocimum basilicum in drought stress conditions and increases the resistance to drought stress with improvement of proline, protein and catalase activity in germination phase.
Comparison Of Empirical Models For Estimating The Mineralization Potential Of Soil Nitrogen
Authors: Bensid Zoubeir 
Published: August 2018

Modeling is an attempt to describe a natural event mathematically. The modeling of N mineralization process has a dual interest, agronomical and ecological. The objective of this study is to evaluate several mathematical models to describe the nitrogen mineralization process of soil samples. These samples were collected from 34 sites spatially distributed in the semi-arid region of El-Madher (the Aures area, north-east of Algeria). Using an auger, the systematic surveys have been carried out and composite samples of soils were collected in the field, and subjected to physical and chemical analyzes. In order to track the kinetic organic nitrogen mineralization, similar samples were collected and taken into cool boxes have been incubated in laboratory, sieved (2 mm) and stored at 4°C before use and then incubated at 28°C for 56 weeks. To facilate comparison, all results have been statistically analyzed, by nonlinear regression and analysis of variance method. Four empirical models were tested to fitt the value found experimentally. The linear kinetics model Nm=k t Ni, the single first-order kinetics model (MI) Nm = Ni e-kt + No (1 - e-kt), the double first-order and the exponential kinetics model (MII) Nm=Ni e-kt + No (1 - e-kt) + e-ht and the hyperbolic kinetics model (MH) Nm=NoH.t/(Tc+t) Ni were used to simulate the cumulative mineralized N (NH4+-N and NO3- -N) in the laboratory incubation. In order to test the performance and robustness of the different models three goodness of fit (coefficient of determination R2, Root Mean Square RMS and Mean Relative Error RMSE) were used. Moreover, the parameters obtained by the different models determined the predictions of nitrogen mineralization. The best results were obtained using the double first-order and exponential kinetics model. The results showed no significant difference between nitrogen mineralized for 56 weeks and nitrogen predicted by various models. However, the N predicted by the MII appears to be the best compared to other models. Indeed, the overestimation of nitrogen potentially mineralizable (N0) obtained by this model was relatively lower than other models. This has been confirmed by the study of multiple correlations between net mineral nitrogen and nitrogen predicted by each model. Thus, the results obtained showed a strong positive correlation between mineralized nitrogen values and those of nitrogen predicted by the different models. The correlation coefficients values indicate the folowing order MII (r = 0.878)> MI (r = 0.748)> MH (r = 0.709). The MII model has, therefore, highlighted that two pools of organic matter that mineralize simultaneously were detected in soil. One pool is stable and the other one is labile. One pool evolves with first-order kinetics and the other with exponential kinetics.
