THE TURKISH IDENTITY CRISIS IN THE NEW LIFE BY ORHAN PAMUK
Abstract. The New Life as a delightful novel of ideas serves as a parable for modern Turkey. This studyexplores how issues of Turkish identity and social reality set up allegorical events that guide the story. Orhan Pamuk evokes the contemporary problem of national identity in Turkey by managing the main characters to enter the world of the mysterious unnamed book. The New Life doubts about all ideological doctrines surrounded Turkey between the tragic absurdities of its past and present, and the hidden clash between Eastern historical values and Westernization by criticizing of globalization and multinational corporate expansion which characterizes Turkey today. Thus, this study attempts to prove the facets that Orhan Pamuk used in his novel to define Turkish national identity.Keywords: Identity, Turkey, Westernization, Orhan Pamuk, Turkishness
Evaluation of multi-walled carbon nanotubes performance in adsorption and desorption of hexavalent chromium
In this study, the removal of hexavalent chromium from aqueous solutions using multi-walled carbon nanotubes (MWCNTs) has been investigated as a function of adsorbent dosage, initial Cr(VI) concentration, initial pH, contact time and temperature. Low pH, low initial concentrations of Cr(VI), increasing contact time and high temperature were found as optimal conditions. A comparison of kinetics models applied to the adsorption of Cr(VI) ions on the MWCNTs was evaluated for the pseudo first-order, the pseudo second-order, and Elovich kinetics models, respectively. Pseudo second-order kinetics model was found to correlate the experimental data well. Equilibrium isotherms were measured experimentally and results show that data were fitted well by the BET model. Thermodynamic parameters were estimated and results suggest that the adsorption process is spontaneous, physical and endothermic. The reversibility of Cr(VI) adsorption onto MWCNTs by desorption process and the effect of operating factors such as regeneration solution characteristics, contact time and temperature on this process was investigated. Results show that MWCNTs are effective Cr(VI) adsorbents and can be reused through many cycles of regeneration without any high decreasing in their performance
The Relationship of Vitamin D and Calcium level with Preeclampsia Severity: A Case- control Study
Repair of horizontal root fracture: A case report
ABSTRACT: Horizontal root fractures in permanent teeth are uncommon injuries among dental traumas. The principle of treating horizontal root fractures of permanent teeth is repositioning and fixation of fractured segment. Diagnosis of tooth fractures based on radiographic findings and the fracture healing process are affected by factors before and after injury. The present case reports the treatment of horizontal root fracture located at the apical-third of upper left and right central incisors. Healing was observed at 1 year follow-up examination
Stressors in Dental Students During the Transition from Theory to Practice: A Qualitative Research
Dentistry is one of the most challenging, demanding, and stressful fields of study. Dental students are expected to acquire various skills, including academic, clinical, and interpersonal skills. This study aimed to investigate the stressors in students during the transition from theory to practice through qualitative research methods and ultimately improve curricula used for learning. This cross-sectional study was performed on fourth to sixth year students of Kerman Dental School through interviews. Interviews related to the experienced clinical stress and challenges and experiences in the clinical environment were conducted with 40 students (16 males and 24 females) who were randomly included in the study and the participants' statements were recorded with their consent. The interview continued until the stage of information saturation and at the end it was confirmed by the participants in the study. Qualitative data were analyzed based on content analysis and then the data were classified. In this study, 8 people were in the fourth year, 16 people were in the fifth year and 16 people were in the sixth year. According to the statements and experiences of students, stressors such as reprimand and lack of time were the most common causes of clinical stress. Other factors, such as professors' attitudes and infection control, also had a significant effect on stress. Patient related factors such as not having a patient, their late or late arrival, and being harassed at work were also cited as causes of stress. Many factors in the clinical environment play a role in the stress of dental students, which can be eliminated or reduced to greatly contribute to the quality of education. According to the results of this study and the recognition of stressors in the clinical environment, more attention of the authorities to this field and the need to review clinical education seems necessar
Validation of a Persian Short-Form Version of a Standardised Questionnaire Assessing Oral Cancer Knowledge, Practice and Attitudes Among Dentists
Objectives: Oral cancer is a global health problem; however, many dentists lack the necessary skills, knowledge and capacity to diagnose oral cancers early. This study aimed to examine the validity and reliability of a Persian short-form version of a standardised questionnaire to assess dentists’ knowledge, practice and attitudes towards oral cancer. Methods: This cross-sectional analytical study was carried out in May 2015 in Tehran, Iran. An original 39-item English-language questionnaire developed by Yellowitz et al. was translated into Persian using forward and backward translation methods. A total of 15 dental professionals were asked to assess the questionnaire for content validity. Based on their feedback, a 20-item short-form version was prepared, including six demographic, six knowledge, four attitude and four practice items. The translated short-form questionnaire was subsequently distributed to 973 general dental practitioners attending a dental conference in Tehran. Internal consistency and reliability were assessed with Cronbach’s alpha coefficient and item-total correlation calculations. Results: A total of 13 professionals and 313 general dentists participated in the study (response rates: 86.7% and 32.2%, respectively). After the elimination of six items (two knowledge, two attitude and two practice items), the validity and reliability of the questionnaire was confirmed. Conclusion: The final Persian 14-item version of the questionnaire had acceptable validity and internal consistency. These results indicate that researchers can use this translated short-form version to evaluate oral cancer knowledge, attitudes and practices among Persian-speaking dentists; this will allow for a comparison of data between different populations
Toward a Modeling Framework for Organizational Competency
Part 6: Computational Systems ApplicationsInternational audienceCompetency modeling framework serves as a; (a) very important basis for the explanation of a generic competency modeling approach, (b) base element in the consolidation of existing knowledge in this area, (c) tool for model developers on selecting appropriate competency models, and (d) basis for competency modeling. This research uses literature review approach to propose a modeling framework for organizational competency. The proposed modeling framework has been developed based on the most relevant well known competency models. The research suggests that organizational competency can be categorized into three groups; individual competency, enterprise competency and collaboration-oriented competency. For modeling each of these groups, it is essential that the modeling process have to be aligned with model developer purpose (Modeling perspective), thus the model developing process will be based on the same segmentation model. Furthermore, competencies have to be model at different levels of abstraction (modeling intent)
