Analysis of the impact of the board of directors as a central governance body on the performance of Moroccan banks

This study aims to analyze empirically the impact of the board of directors as an internal governance mechanism on the performance of Moroccan banks, based on its various roles and, above all, the specific features of bank governance. Empirical validation is obtained by econometric modelling using panel data constructed from 6 Moroccan commercial banks listed on the Casablanca stock exchange and observed for a period of 10 years, from 2012 to 2021. We attempt to detect the impact of bank governance characteristics, through the study of board structure, on bank performance. Our results show the absence of a significant link between the characteristics of the Board of Directors and the performance of Moroccan banks expressed by ROA and ROE. On the other hand, the size of the bank and the capital have a negative impact on the ROA of the banks in our sample. Our study also shows a negative and significant relationship between ROE and bank size. &nbsp

Keyfi Dinamik İç Basınç Altındaki Heterojen Dairesel Yapıların Elastik Ve Viskoelastik Davranışları

Konferans Bildirisi -- Teorik ve Uygulamalı Mekanik Türk Milli Komitesi, 2015Conference Paper -- Theoretical and Applied Mechanical Turkish National Committee, 2015Bu çalışmada, fonksiyonel olarak derecelendirilmiş malzemelerden (FDM) yapılmış eksenel simetrik yapıların zorlanmış titreşim çözümlerinde yeni bir yaklaşım ortaya konulmuştur. Heterojen olması bakımından malzeme radyal doğrultuda fonksiyonel olarak derecelendirilmiştir. Derecelendirme fonksiyonu radyal koordinatlarda keyfi sürekli bir fonksiyon olabilir. İç sınırlara uygulanan dinamik basınç fonksiyonları ise impulsif ya da zamana bağlı keyfi sürekli bir fonksiyon olabilir. Bu koşullar altında cismin davranışını idare eden diferansiyel denklemin değişken katsayılı bir denklem olmasına neden olur. Bazı basit derecelendirme fonksiyonları ve iç basınçları dışında, bu tür denklemlerin analitik çözümlerini bulmak mümkün değildir. Bu durumda problemlerin çözümü ancak sayısal yaklaşımlarla bulunabilir. Bu çalışmada sunulan yenilik, çözümlerde Laplace dönüşümü ile Tamamlayıcı Fonksiyonlar Yönteminin (TFY) birlikte kullanılmasıdır. Laplace dönüşümü uygulanarak, zamandan bağımsız hale dönüşen sınır değer problemi Tamamlayıcı Fonksiyonlar Yöntemi ile Laplace uzayında çözülür. Sonuçların zaman uzayına ters dönüşümleri ise, modifiye edilmiş Durbin yöntemi ile yapılmıştır. Viskoelastisite durumunda ise, Laplace uzayında malzeme sabitlerinin basit bir şekilde değişimi ile kolayca modellenmektedir. Sonuçların doğruluğu ve sayısal çözümlerin yakınsamalarının kontrolü literatürde bulunan referans çalışmalar ile kıyaslanarak yapılmıştır. Basit, etkili ve iyi yapılandırılmış olan çözüm adımları silindir, disk ve küreler için kolayca uygulanabilmektedir

Impact de la structure de propriété sur la performance des banques marocaines cotées

La structure de propriété constitue avec les caractéristiques du conseil d’administration les deux grandes familles de mécanismes interne de la gouvernance. Ces mécanismes ont une importance cruciale, aussi bien pour la firme non bancaire que pour la banque. Dans ce cadre, nous nous suggérons d’identifier l’impact des mécanismes liés à la structure de propriété (notamment la concentration de capital, présence d’actionnaire salarié, participation des investisseurs étranger, participation des investisseurs institutionnels et la participation de l’Etat dans le capital) sur la performance des banques Marocaines exprimée par le ROA et le ROE. L’étude est conduite sur un échantillon constitué des banques marocaines cotées en bourse de Casablanca sur la période 2012-2021. Nos résultats montrent qu’à l’exception de l’actionnariat salarié, en tant que variable explicative et des variables de contrôle, les mécanismes de gouvernance liés à la n’exercent pas un effet significatif ni sur le rendement des actifs ni sur le rendement des capitaux propres. Mots clés : Structure de propriété ; mécanismes internes de gouvernance ; performance bancaire ; rendement des actifs ; rendement des capitaux propres.   &nbsp

Indirect Sliding Mode Control for DC-DC SEPIC Converters

This article presents an indirect sliding mode control (SMC) for single-ended primary-inductor converters (SEPIC). Unlike the conventional SMC methods, the proposed SMC method employs a sliding surface function based on the input current error only. The use of such sliding surface function not only simplifies the implementation but also reduces the cost of implementation. It is shown that the output voltage control can be achieved indirectly. The input current reference is generated by a proportional-integral (PI) regulator. The existence condition and the region of the closed-loop system are determined for all possibilities of the PI gains. The performance of the proposed SMC method is investigated on a laboratory prototype converter, operated in buck and boost modes, in terms of the voltage regulation ability under abrupt changes in the input voltage and load resistance. Simulation and experimental results are presented and discussed

The Effects of Diminishing Family and Community Ties on the Elderly in Ghana

Over the years, family and community ties in Ghana have been a major guarantor of support provision for older persons, especially those who reside in rural areas. While the support provided by family and community members has proved to be vital in enhancing the well-being of older persons, it is also clear that the ties that exist between these sources of support and older persons are gradually diminishing. This paper highlights some implications that come with the gradual decline of communal and familial bonds for older adults

An Effective Model Predictive Control Method With Self-Balanced Capacitor Voltages for Single-Phase Three-Level Shunt Active Filters

This paper presents an effective model predictive control (MPC) method for single-phase three-level T-type inverter-based shunt active power filters (SAPFs). The SAPF using T-type inverter topology has not been reported in the literature yet. Contrary to most of the existing MPC methods, the proposed MPC method eliminates the need for using weighting factor and additional constraints required for balancing dc capacitor voltages in the cost function. The design of cost function is based on the energy function. Since the factor used in the formulation of the energy function does not have any adverse influence on the performance of the system, the cost function becomes weighting factor free. The weighting factor free based MPC brings simplicity in the practical implementation. The effectiveness of the proposed MPC method has been investigated in steady-state as well as dynamic transients caused by load changes. The theoretical considerations are verified through experimental studies performed on a 3 kVA system
