Assessing The Relationship Between Liberalization, Ownership And Performance: The Case Of Turkish Banks

This paper employs a DEA-type Malmquist index approach to evaluate the impact of financial liberalization on the productivity changes of public, private and foreign banks in Turkey during the period between 1981 and 1990. The results indicate that all forms of banks have benefited from financial liberalization. However, foreign banks were found to be the most productive, followed by private banks and public banks respectively. The major source of productivity gains is scale changes for public and private banks and technical progress for foreign banks. It also seems that productivity growth indices of all banks converge towards the end of liberalization period

Ki-67 Labeling Index in Primary Invasive Breast Cancer from Sudanese Patients: A Pilot Study

Ki-67 labeling index has been linked to patient outcome in breast cancer patients. However, very few published reports have examined Ki-67 labeling index in African breast cancer patients. Sixty-two Sudanese breast cancer patients with primary invasive tumors were immunostained for Ki-67, ER, PR, Her-2/neu, CK5/6, and CK17. Ki-67 labeling index ranged from 0% to 50%, with a median of 5% (interquartile range 0–10). Low Ki-67 labeling index (immunostaining < 10%) was detected in 43/62 (69.4%) with a median of 0 (interquartile range 0–5), whereas high Ki-67 labeling index (immunostaining ≥ 10%) was revealed in 19/62 (30.6%) with a median of 20 (interquartile range 12–26). Ki-67 labeling index was significantly associated with tumor grade (P=0.022, Mann-Whitney U Test). There were no significant group differences between Ki-67 labeling index and ER (P=0.43), PR (P=0.7), Her-2/neu (P=0.45), CK5/6 (P=0.29), CK17 (P=0.55), pathologic stage (P=0.4), tumor histology (P=0.99), breast cancer subtypes (P=0.47), tumor size (P=0.16), and age at diagnosis (P=0.6). These results suggested that Ki-67 labeling index correlates with tumor differentiation and not with the tumor size or any other tested marker in Sudanese breast cancers. Thus, Ki-67 labeling index could be considered as a reliable measure of tumor proliferative fraction in Sudan

Reviewing the Van Hiele model and the application of metacognition on geometric thinking

Metacognition, or the ability to think about thinking, is essential in the development of geometric thinking. However, studies on the Van Hiele model and the application of metacognition on geometric thinking are still under-researched. This study aimed to provide a review of the Van Hiele model and the application of metacognition on geometric thinking. A total of 844 articles were retrieved through internet search engines from 1995 to 2020 and manually selected and reviewed systematically. The keywords used related to the Van Hiele model, metacognition, and geometric thinking. The findings that emerged from the review were categorized into two main themes which were the effectiveness of the Van Hiele model towards geometric thinking and the effectiveness of the application of metacognition on geometric thinking. Most articles revealed the positive indication of the geometric thinking development through the Van Hiele model intervention. It also seems that the potential of the application of metacognition in the Van Hiele model can strengthen geometric thinking development. Researchers and educators may find this knowledge useful in conducting empirical studies and developing learning instructions based on the application of metacognition in the development of geometric thinking

Experimental realization of quantum teleportation algorithm via electrical circuits

4th International Conference on Advances in Physical Sciences and Materials 2023, ICAPSM 2023 -- 17 August 2023 through 18 August 2023 -- Hybrid, Coimbatore -- 200383Quantum teleportation is one of basis study of quantum computing algorithms mostly used in quantum communication. This algorithm has so far been implemented using a variety of quantum realization models. In this study, quantum teleportation algorithm is realized experimentally using classical LC circuits. In addition, electrical simulation of some quantum gates such as Hadamard and CNOT gates used in algorithm are also given. The importance of implementation of such quantum algorithms onto classical electrical circuit is that it is being inexpensive and can work at room temperature. This study can contribute greatly to the experimental teaching of the emerging quantum technology revolution to students

The Effects of Psychological Contract Breach on Job Satisfaction Among University Employees in Pakistan: Moderating Role of Perceived Organisational Support

This paper investigated the relationship between psychological contract breach (PCB) and job satisfaction (JS) having perceived organisational support (POS) as a moderator. This study employed social exchange theory and organisational support theory to examine PCB, JS and POS relationship. Date collection was made with the help of a self-administered questionnaire from five public sector universities across Pakistan. A sample of 1230 was used for this research study. About 739 valid respondents participated in this research. Structural equation modelling and IBM AMOS was used to carry out analysis. Results showed that PCB led to job dissatisfaction; however, POS did not moderate this relationship. Limitation of this research was its being cross-sectional. A longitudinal study is proposed. Researchers, practitioners are urged to understand PCB, JS and POS relationship in order to have a good employee-employer relationship much needed for the high performance work systems (HPWS

Kuantum Bilişim Teknolojileri Kullanılarak Kuantum Ağ Simülasyon Yazılımı Geliştirilmesi

01.11.2021Bu proje kapsamında ilk olarak kuantum ağlar alanında günümüzde var olan deneysel çalışmalardan biri olan Tokyo Kuantum Ağı mevcut kuantum ağ simülatörlerinde test edilmiştir. SQUANCH, QuNetSim ve SimulaQron ağ simülatörlerinde gerçekleştirilen test sonuçlarına göre Tokyo Kuantum Ağ simülasyonu performans olarak en iyi SQUANCH ağ simülatöründe gerçekleştirilebileceği sonucuna varılmıştır. İkinci olarak da kuantum iletişim için güvenli bir kuantum ağ topolojisi önerilmeye çalışılmıştır. Bu çalışma aynı zamanda SQUANCH ağ simülatöründe de test edilmiştir. Elde edilen sonuçlar önerilen ağ topolojisinin güvenli bir kuantum iletişim için kullanılabileceğini göstermektedir. Üçüncü olarak da mevcut simülatörlerden üstün bir kuantum ağ simülatörü geliştirilmeye çalışılmıştır. Geliştirilen simülatör hem gürültünün hem de saldırganın dinamik olarak simülasyonun içinde olması bağlamında diğer simülatörlere göre üstündür. Bunula birlikte geliştirilen simülatör diğerlerinden faklı olarak her platformda çalışabilme özelliğine sahiptir. Yapılan test sonuçları genel olarak değerlendirildiğinde geliştirilen simülatörün üstün özellikleri açıkça ortaya çıktığı görülmektedir
