Abstract: One of the perspectives of delving women in academia is by using Sustainable Development Goal (SDG) goal 4 ‘Ensure inclusive and equitable quality education and promote lifelong learning opportunities for all’, to measure the SDG number 5, ‘Achieve gender equality and empower all women and girls’ - and the vice versa. The extent of Millennium Development Goals (MDGs) realization provides lessons that the current and future education policies and programs are/ will be founded on. To achieve a thorough analysis, consistently accurate and relevant data is requisite and essential to monitoring and evaluating the real effects of education policies on women empowerment. At a glance, the average children enrolment in primary education rose remarkably between 2000-2015 in most developing countries indicating the extent of achievement of MDGs. Shifting from these quantitative evaluation results, this study outlines qualitative perspectives of measuring women in leadership in the education sector as an approach of empowerment. A key concern is how the generation of data through monitoring and evaluation enables fast-tracking of the effects of the policies on women empowerment in the education system. In this article, we focus on three school management variables as measures of women empowerment: 1) the nature of both internal and external audits to ensure accountability and transparency; 2) professionalism enhancement (nature of the In-service education training), and 3) the analysis of resource needs in empowering women. While doing the monitoring and evaluation of SDGs achievement, there is a need to deepen the analysis and consider the processes that determine which gender elevates to leadership.

Abstract: The question of whether institutional quality is an important driver of growth has been the subject of a growing literature in both developed and developing economies across the globe. This study revisits this relationship in Nigeria from 1981Q1 to 2016Q4 and discusses the relevant policy implications for post Covid-19 Nigeria. The study adopted the ARDL approach which uses a bounds test approach based on unrestricted error correction model (UECM) to test for a long run relationship among the relevant variables. The findings indicate that institutional quality impacts negatively but insignificantly on growth in Nigeria, both at the aggregate and sectoral levels. However, initial output growth levels, capital and labour were found to be important drivers of growth in the country, while trade is growth-retarding. The study concludes that in this post Covid-19 era in Nigeria, there is need to improve the quality of socio-economic and political institutions in the country so that a more robust impact of these institutions can be felt in the economic performance of the country both at the aggregate and sectoral levels.

Abstract: For the majority of Internet users, the Networkrepresents the endless source of opportunities that enhance wellbeing.For some though, it might be the reason that makes them“sick” with symptoms specific to mental disorder. This condition iscalled Internet addiction and is described as “impulse control disorderthat does not involve addictive substance”. In recent years SocialNetworking Sites (SNSs) have provided many and significantbenefits to users. At the same time, though, there are risks with theiruse, such as excessive use that can lead to addiction phenomena aswell as contribute to the manifestation of Internet addiction. Thepresent study investigates the phenomenon of Internet addiction inadult Greek users of Social Networking Sites, to determine theprevalence of IA among SNS users, and investigates the correlationof socio-demographic factors with the occurrence of IA in SNS users.The results showed that there is connection between the use of SNSand IA, and the prevalence of IA among SNS users reaches 30%.Moreover, IA relates to the age of SNS users.
Title of the Paper: A System Dynamics Simulation Study on the Efficiency of Commercial Banks from the Perspective of Green Credit
Authors: Fang Chen, Kun Zhang, Li Wang

http://doi.org/10.46300/9103.2020.8.5
Abstract: With the deepened commitment to the green credit policy and increasingly intense competition among commercial banks, the impact of green credit on the efficiency of commercial banks has attracted great attention from the banking industry and governments. To study the efficiency of commercial banks from the perspective of green credit, this paper, with a case study on Bank of Shanghai, builds a system dynamics model to present the causal loop diagram and system flow diagram and seek the functional relations between variables. Then it goes on to simulate the evolution of the policy situation with system dynamics and attempts to find out the change path and evolution direction of green credit and variables regarding bank efficiency when a certain policy is adjusted, with a view to providing theoretical basis and data support for formulation of financial policies and selection of bank strategies.
Title of the Paper: Stock Forecasting using Combination of Continuous Wavelet Transform and Neuro-Fuzzy Systems
Authors: M. Golchin
Pages: 24-27
http://doi.org/10.46300/9103.2020.8.4
Abstract: Stock market forecasting is an important challenge for clients, so it attracts researchers to introduce new and reliable approaches to forecast this market. There are many approaches using wavelet decomposition to access details and approximation of stock market data and on the other hand, using neuro-fuzzy systems can be useful to overcome the uncertainty of data for forecasting. In this study, a hybrid approach will be introduced that is a combination of continues wavelet decomposition and neuro-fuzzy system to predict stock market data. For this aim, first data is normalized between 0 to 1 and decomposed by continues wavelet decomposition and data of each sample time was used to forecast “n” sample forward and finally, this approach was evaluated. For evaluating the performance of this approach, index of petroleum products of Tehran stock market between March 2015 to September 2019 was used and five steps of forecasting were considered. The best performance was 6.64x10-5 for one step forward forecasting and the worst was 4.74x10-4 for five steps forward forecasting. Results showed that, increment of forecasting step causes decrement of forecasting precision however it is reliable.
