Abstract: Although open access has steadily developed with the continuous increase in subscription journal price, the effect of open access articles on citations remains a controversial issue. The present study empirically examines the factors determining authors' choice to provide open access and the effects of open access on downloads and citations in hybrid journals. This study estimates author’s choice of open access using a probit model, and the results show that the cost of open access is an important factor in the decision. After a test for endogeneity of open access choice, the equation for downloads is estimated with the variables representing characteristics of articles and authors. The results of estimating downloads by ordinary least squares show that open access increases the number of downloads in hybrid journals. On the other hand, from citation estimations using a negative binominal model, this study found that the effect of open access on the number of citations differs among hybrid journals. It is a good practice for authors to consider a balance between article processing charges and the benefits that will be gained from open access when deciding whether to provide open access.

Abstract: This study has been performed on the reality of the economic dimensions of China Investments in Africa during the period between (2000-2015). The Study adopted the descriptive analytical method by standing on the volume and the type of Chinese investments in the African continent. The study focused on the returns of these investment and the related exchange relations, on the economies of the African countries. The study found that the Chinese investments in Africa are direct investments that influenced the size and nature of the exchange between the two parties, which has been in favor of China's balance of trade. The study confirmed the increase of Chinese investments in the continent during the period (2000 -2013) but these investments began to decline thereafter. The study attributed this decline to the slowdown of China economy, instability in different African countries, in addition to the economic pressures exerted by western countries. All this has led to the decline in investments & exchange with the countries of the continent in general. In addition the study has reported that Chinese investments were concentrated on the field of natural resources and energy, which led to uneven impact on the economic indicators of the continent countries (poverty rates, GDP, growth rate & balance of trade. est.). In conclusion the study recommended that Chinese investments in Africa should be taken with more studies and analysis & with some additional control, monitoring and evaluation. Also African countries should re-evaluate their regional economic alliances and entities to avoid contradiction & lack of coordination in their investments policies, especially when dealing with foreign investments.
