Auteur(s): Chehat Ouahiba; Akacem Kada
Résumé: This paper examines the impact of tourism on economic growth and development in Algeria by using the causality analysis among real gross domestic product, real international tourism earning, human capital and gross fixed capital formation. A multivariate autoregressive VAR model is applied for the examined period 1995-2015. The results of cointegration analysis suggested that there is one cointegrated vector among the four variables, Economic Growth (RGDP), Tourism Earning (RITR), Human Capital (SCH) and Gross Fixed Capital Formation (GCH). Granger causality testes based on error correction models (VECM), have indicated that there is a “one-way causality” relation between international tourism earnings and economic growth

Auteur(s): Touahir Abdeldjalil; Bendob Abdellah
Résumé: This study aim to reveal the effectiveness of the distance learning style through the opinions of
doctoral students. This study was based on an electronic questionnaire (Google Drive) for 42
students from the two institutions. The most important results were that there is a mean trend of
satisfaction among the respondents in interactive distance learning, continuity of distance education
and students' interaction in the use of distance education, while it should be noted that there are
obstacles to using distance education
Finally, the researchers recommended organizing distance education training courses for teachers
and students, work to remove obstacles, the need to combine physical education (without media)
and distance education in higher education institutions in the future.

Auteur(s): Sadouni Mohammed; Keddam Djamel; Boumimez Fayçal
Résumé: This study examines the existence of a causal relationship between the Saudi stock market and Oil prices (Brent oil, WTI crude oil, OPEC basket prices). Saudi Arabia is OPEC’s largest oil producer. Using a daily dataset covering the period from 2 January 2019 to 30 March 2022, we find that most studies show oil price volatility transmits to stock market volatility. We used the co-integration approach of Johansen-Juselius (1990) and the causality test ( Granger, 1969, Sims,19972). We found the existence of direct Granger causality from the Saudi stock markets (TASI) to oil prices (BRENT and OPEC basket price)
