Culturally relevant/sustaining pedagogy in a diverse urban classroom: Challenges of pedagogy for Syrian refugee youths and teachers in Turkey     

Nihat Kotluk  Hasan Aydin 《British Educational Research Journal》2021,47(4):900-921

This study focused on whether and how teachers implemented the principles of culturally relevant and sustaining pedagogies and the challenges teachers faced while trying to implement these principles with Syrian students in Turkey. The study was built on the four components of pedagogies: academic achievement; cultural competencies; sociopolitical consciousness; and the sustainability of culture. Qualitative data were obtained through interviews and field notes with four teachers who had Syrian students in their classes and four Syrian students. Content analysis was used to examine the data. The findings revealed that both teachers and students had low expectations of academic achievement. Teachers conducted the teaching–learning process entirely according to the perspectives of students who were from the mainstream culture. Teachers tried to improve the cultural competencies and enhance their sociopolitical consciousness of the Syrian students; however, the attempts were limited and inadequate. Although teachers were aware of the importance of sustaining the Syrian culture, they did not know how to do so. The teachers did not have sufficient competencies or experiences to make revisions or to carry out an effective instructional process tailored to the needs of Syrian students because of an absence of skills and knowledge of multicultural education.  相似文献

Respect in principal–teacher relations at primary schools in Turkey     

Sabri Güngör  İnayet Aydın  Hasan Basri Memduhoğlu  Ebru Oğuz 《International journal of qualitative studies in education》2013,26(10):1349-1372

Respect means consideration of actions and requests of others and confirmation of values of others. School is a social institution where students are equipped with knowledge and skills, as well as fundamental character attributes. Respect among students, teachers, administrators, parents, and other staff at schools is of importance. In this study, the focus group method, including 12 principals and 10 teachers at state primary schools, was employed to explore respect in principal–teacher relations. According to the findings, the participants generally developed professional respect understanding. The teachers presented different definitions of respect associated with hierarchical relations. The participants’ respect behaviors were commonly observed in positive communication and self-improvement. The principals displayed respect for teachers through some guarding behaviors, and the teachers displayed profession-related respect behaviors. The common respect expectations of the participants were as follows: self-improvement, establishment of positive social relations, and unbiased behavior. While the school principals expected obedience and complete fulfillment of assigned tasks from teachers, the teachers expected civility, justice, and guarding administration from principals. The participants regarded improper appearance, behaviors contradictory to rules of good manners and bad habits as disrespectfulness. The school principals regarded abuse of goodwill and false excuses by teachers as disrespectfulness; whereas the teachers regarded oral or behavioral insults by school principals and intervention in their private life as disrespectfulness.  相似文献   

An Investigation into the Parameters Affecting Preparation of Polybutyl Cyanoacrylate Nanoparticles by Emulsion Polymerization     

Hasan Ebrahimi Shahmabadi  Seyed Kazem Bagherpour Doun  Seyed Ebrahim Alavi  Mehri Mortazavi  Zahra Saffari  Maryam Farahnak  Azim Akbarzadeh 《Indian journal of clinical biochemistry : IJCB》2014,29(3):357-361

Emulsion polymerization was used to synthesize poly butyl cyanoacrylate nanoparticles in presence of steric stabilizer dextran 70. Nanoparticles were characterized by particle size analysis, scanning electron microscopy and light microscopy. Polymerization factors affecting particle size and distribution such as dextran 70, polysorbate 80 (PS 80) and H⁺ concentration, polymerization time and temperature, and sonication were studied. Distinct concentrations of stabilizer were needed to produce proper nanoparticles. In this case, the appropriate value was 2 % of total volume. At pH 4 significant decrease in production efficiency demonstrated the substantial effect of H⁺ concentration on nanoparticles. Furthermore significant increases in particle size and distribution was observed at 50 °C compared to room temperature. 0.001 % (v/v) PS 80 represented notable influence on size and distribution. In addition, shaped nanoparticles were obtained by altering polymerization time from 5.5 h to 18 h. Finally, nanoparticle features were influenced by different factors. Appropriate manipulating of such factors can lead to obtaining desirable nanoparticles.  相似文献

Cascade design for formation control of nonholonomic systems in chained form     

Jawhar Ghommam  Hasan Mehrjerdi  Maarouf Saad 《Journal of The Franklin Institute》2011,348(6):973-998

This paper presents a constructive method to design a cooperative state and output feedback to steer a group of nonholonomic mobile robots in chained form to form a desired geometric formation shape. The control methodology divides the resulting tracking error dynamics into a cascaded of linear and time-varying subsystems. A basic consensus algorithm is first applied to the linear subsystem which makes the states synchronize exponentially to zero. Once this first linear subsystem has converged, the second cascade can be treated as a linear time-varying subsystem perturbed by a vanishing term from its cascade. A dynamic state and output feedback is constructed to achieve synchronization of the rest of the states. The proof of stability is given using a result from cascade systems. Since time delay appears in many interconnection networks and particularly in cooperative control, its effect on the stability of the closed-loop system is analyzed using Razumikhim theorem. It is shown that the established cooperative controller work well even in the presence of time delay. Numerical simulations are performed on models of car-like mobile robots to show the effectiveness of the proposed cooperative state and output-feedback controllers.  相似文献   

Stable model predictive control for a nonlinear system     

Akbar Rahideh  M. Hasan Shaheed 《Journal of The Franklin Institute》2011,348(8):1983-2004

In this paper, a stable model predictive control approach is proposed for constrained highly nonlinear systems. The technique is a modification of the multistep Newton-type control strategy, which was introduced by Li and Biegler. The proposed control technique is applied on a constrained highly nonlinear aerodynamic test bed, the twin rotor MIMO system (TRMS) to show the efficacy of the control technique. Since the accuracy of the plant model is vital in MPC techniques, the nonlinear state space equations of the system are derived considering all possible effective components. The nonlinear model is adaptively linearized during the prediction horizon. The linearized models of the system are employed to form a linear quadratic objective function subject to a set of inequality constraints due to the system input/output limits. The stability of the control system is guaranteed using the terminal equality constraints technique. The satisfactory performance of the proposed control algorithm on the TRMS validates the effectiveness and the reliability of the approach.  相似文献

Authorship conflict in Bangladesh: an exploratory study     

Hasan Shareef AHMED  Abdullahel HADI  Nuzhat CHOUDHURY 《Learned Publishing》2010,23(4):319-325

This study aimed to explore the causes, types, and consequences of authorship conflicts among the researchers of selected research institutions in Dhaka, Bangladesh; and to suggest ways to reduce conflicts. A sample of 100 researchers was given a semi‐structured questionnaire; 45 subjects responded. The responses were confidential and anonymous. Over two‐thirds of the respondents were aware of authorship conflicts, and one‐third had actually faced conflicts with their co‐authors. Of them, four faced conflicts with their juniors, while 13 faced conflicts with their seniors or supervisors. The primary causes of such conflicts appear to be unethical claims of authorship, violation of authorship order, and deprivation of authorship. In most cases, the victims became frustrated and had to give up, and avoided a direct clash to safeguard their job. Four respondents claimed to have been victimized for raising their voice. Conflict was never resolved in seven cases. To reduce conflicts, respondents suggested that authorship should be decided before the study begins, order of authorship must be determined according to contribution, and a standard code of authorship should be followed strictly. Authorship conflicts arise among researchers mostly due to what they regard as unethical practice of their co‐authors, supervisors, and department heads in the absence of any formal authorship policy in the institutions. A standard code of authorship, sensitization of researchers to the problem through open discussions and advocacy, and formation of a grievance redress committee are suggested to minimize such conflicts. Although the sample size was small, some of the specific recommendations will be appropriate in many other cases.  相似文献
