Through this paper, we aim to measure the impact of economic growth on unemployment, in the short and long term in the Algerian economy during the period 1970-2017. To achieve this objective, the Okun relationship was applied, and then the Okun relationship developed by Gordon was estimated, relying on ARDL model methodology in the estimation with the aim of estimating short- and long-term elasticities;  The most important results of this study were: - The effects of the change in output growth on unemployment are not immediate, in the sense that the GDP growth rate in period (t) does not affect the rate of unemployment growth in the same period in the two models, but it's highly influential in late-time periods. - There is a negative and significant  effect  of GDP growth rates on unemployment in both models and in the long and short term, Where we found that the elasticity of unemployment relative to output growth is estimated at -0.73% in the first model, and -0.44 points in the second model. Finally, through this study, we found some areas of weakness in the national economy, so we offer some recommendations, the most important of which are: The need to provide an integrated database on unemployment that takes into account  international definitions and measurements; Implement serious policies that achieve a sustainable economic growth; Attention to the productive and social services sectors that are most absorbing labor,  The necessity of adopting the principle of future planning for employment.

This study investigates the impact of change management strategies (empirical-rational, normative-reeducative and power-coercive strategies) on investigating competitive advantage (cost, quality, flexibility and delivery). The study was applied on a simple random sample consisted of 222 employees in the Saudi banks of Qassim region. A questionnaire was developed to measure the study variables, it included 43 items, 24 of which measured the three change strategies, and 19 items measured the four competitive advantage dimensions. The questionnaire’s validity and reliability tests were acceptable. Outcomes of the analysis indicate that there is a significant impact of change strategies (empirical-rational and normative-reeducative strategy strategies) on investigating the competitive advantage while there was no a significant impact of applying power-coercive strategy on investigating the competitive advantage of Saudi Banks.

The study aims at surveying and analyzing a reasonable number of studies published in the aftermath of the outbreak of the novel coronavirus (Covid-19). The period covered from January 1st till April 10th, 2020, with a view to revealing the main methodological approaches used, by these studies and reports, to identify the economic implications and/or draw possible scenarios about the likelihood impacts of the pandemic on the global economy. The study identified four approaches: the one based on modeling, economic analysis and scenarios, the comparative approach, the approach based on surveys and polls, and finally the approach based on the results of other sciences; but this approach is very limited and rare. Obtained results show that the widely used approach, in the surveyed studies and reports, is the modeling and economic analysis one, followed by the comparative approach that tries to compare the effects of the past epidemics, and/or financial and economic turbulences with the effects of the ongoing pandemic. Studies agreed that the world economy will experience an economic downturn, but they differed on its form and extent. Some of the studies projected that the recession may take the (V) shape or (U). The current study expects that the (U) shape is the likely eventuality to take place subject to the lessening of the lockdown and social distancing measures by mid-year (i.e. June 2020), and the fact that the virus will not appear in a second or a third wave. If these two conditions are not met, the World economy may face a prolonged recession of the sort of (L) shape.

The research objective is to investigate the extent of efficiency in industrial investment in the Kingdom of Saudi Arabia and the factors affecting it. The research used the deductive approach methodology in the economic analysis in both from the quantitative and descriptive perspectives. Following Klein’s model, and Two Stage Least Squares (2SLS) technique was used for estimation. Among the major findings of the research is the existence of a positive relation between domestic industrial product and government expenditure, the interest rate, credit size and taxes.  In addition, investment was also found to be positively related to aggregate wages in the industrial sector, GDP and technology level.  Further, a positive and statistically significant relation was also found between industrial investment and profits in the industrial sector. The study recommends more incentives, more utilization of industrial investment maps, better exploitation of comparative and competitive advantages to localize industries, developing human capital, articulating partnership forms with the public and private sectors in the field of industry.

The aim of this study was to measure the impact of social marketing campaigns with their two dimensions (cognitive - emotional) on positive health behavior, taking into consideration the mediating role of the awareness of the emerging Corona virus as an intermediate variable,  as well as measure the level of the impact of social marketing campaigns with two dimensions (cognitive - emotional) on positive health behavior when mediating health awareness of the emerging corona virus, and identify The significant differences in the level of health awareness and positive health behaviors related to the prevention of corona virus as a result of some demographic characteristics (qualification, type), by using  the analytical descriptive method, the research problem was formulated in a group of questions, and the data were collected using the Questionnaire using Google Forms, and the size of the community was more than (500) thousand people, and the sample size was estimated (384) sample, and (430) were collected, fit for analysis thereof (418) questionnaire  and the researcher reached many results such as the interpretation of the cognitive and emotional dimension of commercial marketing campaigns. (0.42) of health awareness, and it became clear also that the emotional dimension is the variable that most influences positive health behaviors by (27%), and the positive moral effect of the cognitive dimension of social marketing campaigns on positive health behaviors increases when mediating health awareness by increasing (72%). The effect of the affective dimension of social marketing campaigns increases on positive health behaviors when mediating health awareness, with an increase (45%), and the dimensions of social marketing campaigns explain 0.61% of the explanation of the variation in positive health behaviors, and the two dimensions of social marketing campaigns explain (42%) of the variance The interpreter in healthy awareness. It was also clear that there are no statistically significant differences in health awareness due to the educational level of the sample members, and that there are differences between male and female in health awareness and in positive health behaviors and this difference tends to be female.
