    A DYNAMIC PANEL DATA ANALYSIS FOR RELATIONSHIP BETWEEN TECHNOLOGICAL INNOVATION, ENTREPRENEURSHIP AND ECONOMIC GROWTH
    (Oum-El-Bouaghi University, 2017-06-30) Sadraoui, Tarek; Ammari, Anis
    This manuscript aims to study elements of answers to the effect of adequate entrepreneurial activity that would have effects on economic growth. This paper analyzes the relationship between entrepreneurship and economic growth for a dynamic panel data of developing countries over the 2004–2017 periods. We used two measures of entrepreneurship: the new density and the potential of innovation. We estimated a growth function using the method of static and dynamic panel data. Our results show that the new density and growth are significantly and positively correlated. Our results also show that if the short-term impact of technological innovation on growth is negative, this effect is positive in the long term. This result confirms the theoretical predictions, namely the theory of spillage.

    A NEW HYBRID EXPANSION FUNCTION BASED MUTUAL INFORMATION FOR A MULTILAYER NEURAL NETWORKS OPTIMIZATION
    (Oum-El-Bouaghi University, 2017) Ncibi, Kais; Djenina, Amor; Sadraoui, Tarek; MILI, Faycel
    Function expansion was used to expand initial features based on a non linear transformation. Many known expansion functions are found such the trigonometric, the polynomial, the Legendre polynomial, the power series, the exponential and the logarithmic transformation. This paper present a comparison between different expansion functions based on mutual information and different performance functions. We propose a new expansion process able to improve the correspondent mutual information and the final performance. The process was tested; using different benchmark databases, and shows his ability to improve results of classification problems

    Achieving food and energy security between the current and hoped-for reality
    (University of Oum El Bouaghi, 2023-10-03) Mgadmi, Nidhal; Sadraoui, Tarek
    The purpose of this article is to analyze the interactions between energy and food security, referred to in this study as the energy-food nexus and the impacts of global risks using the Global Risks Report in the current context of successive crises. In this analysis, we reveal that energy and food are interconnected and essential resources that require sustainable, integrated, and intelligent management. These vital resources are vulnerable to many global risks, which are exacerbated by extreme weather events, mass involuntary human migrations and other riskswhich puts vulnerable communities in less developed countries at risk. In conclusion, policies implemented by the international community, decision-makers, civil society, and the private sector must be consistent with targeting and mitigating global risks, specifically, energy and food security. الغرض من هذه المقالة هو تحليل التفاعلات بين الطاقة والأمن الغذائي والمشار إليها في هذه الدراسة بالعلاقة بين الطاقة والغذاء، وتأثيرات المخاطر العالمية باستخدام تقرير المخاطر العالمية في الوقت الراهن فيضل الازمات المتتالية في هذا التحليل، نكشف أن الطاقة والغذاء هي موارد مترابطة وأساسية تتطلب إدارة مستدامة ومتكاملة وذكية. وهذه الموارد الحيوية معرضة للعديد من المخاطر العالمية التي تتفاقم بسبب الظواهر الجوية المتطرفة والهجرات البشرية الجماعية غير الطوعية وغيرها من المخاطر التي تعرض المجتمعات الضعيفة في البلدان الأقل نموا للخطر، وفي الختام فإن السياسات التي ينفذها المجتمع الدولي وصناع القرار والمجتمع المدني والقطاع الخاص، يجب أن تتوافق مع استهداف المخاطر العالمية والتخفيف منها، وعلى وجه التحديد، الطاقة والأمن الغذائي.
