Issues Causing Girls’ Dropout from Schools in Afghanistan

The current study is a non-empirical research attempting to explore the key issues contributing to the dropout of girls from schools in Afghanistan. The paper first provides a historical background where the education of girls in the country has always been challenged. The study also explores a few studies conducted in the neighboring countries of Afghanistan where girls’ education is facing similar challenges causing to their dropout from schools. Subsequently, specific challenges, such as cultural, economic, insecurity, and school related challenges have been identified as the main challenges toward the education of girls in Afghanistan. Finally, a number of recommendation have been proposed at the end of the paper, implementing of which might be useful for the status of girls’ education in the country

Communicative Language Teaching (CLT) in EFL Context: Exploring Afghan EFL Lecturers’ Perceived Challenges in Implementing CLT

Many studies have been conducted to investigate the implementation of Communicative Language Teaching (CLT) in ESL and EFL contexts, but those conducted in EFL context, have reported that the application of CLT was challenging. Still, as far as the Afghan EFL context is concerned, there is a lack of empirical research investigating the issue. Hence, the purpose of this study is to explore afghan EFL lecturers’ perceived challenges in practicing CLT. The study also aims to examine if there is any significant relationship among teachers use of CLT, the perceived challenges, and their demographic profiles. This study uses a quantitative research approach in which a survey questionnaire was given to EFL lecturers teaching in a public university. The results of the study revealed that the EFL lecturers had positive perceptions of using CLT activities, as there were evidence of a number of major CLT activities conducted in their classrooms. The results also revealed that they faced certain challenges that prevented them from implementing CLT effectively. Furthermore, significant correlation was found between students’ related challenges and teachers’ perceptions of using CLT; however, no significant correlations were found among teachers’ demographic profiles and CLT perceived challenges. This research is significant since it could be used as a resource presenting a comprehensive picture of CLT implementation in EFL classrooms in Afghanistan

Averaging Transformations of Synaptic Potentials on Networks

The problem of the transformation of microscopic information to the macroscopic level is an intriguing challenge in computational neuroscience, but also of general mathematical importance. Here, a phenomenological mathematical model is introduced that simulates the internal information processing of brain compartments. Synaptic potentials are integrated over small number of realistically coupled neurons to obtain macroscopic quantities. The striatal complex, an important part of the basal ganglia circuit in the brain for regulating motor activity, has been investigated as an example for the validation of the model

The Predominance of Electric Transport in Synaptic Transmission

The quantitative description of the motion of neurotransmitters in the synaptic cleft appears to be one of the most difficult problems in the modeling of synapses. Here we show in contradiction to the common view, that this process is merely governed by electric transport than diffusion forces

Afghan EFL Lecturers’ Perceptions of Code-Switching

Code-switching is explained as switching between two languages at the same time while conversing in the same discourse. The aim of this study is to explore the perceptions of Afghan EFL lecturers toward code- switching. This study used a qualitative research approach in which the data was collected via semi-structured interviews with five EFL lecturers. The lecturers were interviewed to explore their perceptions and reasons for code-switching, and the extent to which they practice code-switching in their classrooms. The results revealed that the lecturers in the study had positive perceptions of code-switching and believed it as a beneficial strategy in facilitating the learning process. However, they also conveyed that an excessive practice of code-switching should be avoided. The study results also disclosed that the lecturers practiced code-switching for various functions such as explaining difficult concepts (translation), explaining complex grammatical points, clarifications, and giving instructions. Finally, the paper provides recommendation for further research

Directional Relays for Multi-Hop Cooperative Cognitive Radio Networks

In this paper, we investigate power allocation and beamforming in a relay assisted cognitive radio (CR) network. Our objective is to maximize the performance of the CR network while limiting interference in the direction of the primary users (PUs). In order to achieve these goals, we first consider joint power allocation and beamforming for cognitive nodes in direct links. Then, we propose an optimal power allocation strategy for relay nodes in indirect transmissions. Unlike the conventional cooperative relaying networks, the applied relays are equipped with directional antennas to further reduce the interference to PUs and meet the CR network requirements. The proposed approach employs genetic algorithm (GA) to solve the optimization problems. Numerical simulation results illustrate the quality of service (QoS) satisfaction in both primary and secondary networks. These results also show that notable improvements are achieved in the system performance if the conventional omni-directional relays are replaced with directional ones
