This article aims to examine how certain economic and social factors influence short-and long-term performance of small and medium enterprises (SMEs). SMEs' performance is defined by using the value added (VA) by SMEs, as a percent of the total VA by enterprises. The study targets European Union (EU) countries selected by the authors following a cluster analysis procedure. In order to obtain short-and long-term influences, an analysis that carries out three types of tests is conducted: testing stationarity, testing cointegration and testing causality between the indicators identified as influencing factors and the variable measuring the performance of SMEs. The novelty and originality of this research are defined in terms of addressing the performance of SMEs from a new perspective, using an econometric basis in a macroeconomic view. From an econometric perspective, the results are among the most varied, both in the long-and short-term, however they also have a correspondent economic explanation. ARTICLE HISTORY

The relationship between foreign direct investment and economic growth is a relationship that has long been studied in the economic literature, of particular importance for the economic and social development of any nation. The main objective of this paper is to analyze the scientific output in this scientific area, based on a bibliometric analysis, in order to identify some trends and to explain some phenomena within the economic reality. The paper analyzed 2281 documents from the Scopus database, using tools provided by the aforementioned database, VOSViewer and Citespace software. The analysis was carried out on several levels: typology of information dissemination, thematic area of publications, temporal/geographical distribution of documents and their scientific content. Among the findings authors can mention that the connection between foreign direct investment and economic growth is very strong (according to the cluster analysis in VOSViewer); consequently, the focus of the authors migrated from general economic aspects of the relationship to the elements of ecology and environmental protection. Going deeper with the analysis, conducting two parallel analysis of the papers with highest citation burst and keywords with highest citation strength values, some interesting trends were found in the relationship between foreign direct investment and economic growth.

The main purpose of this study is to survey the scientific literature and try through bibliometric means to position the concept of organizational culture (OC) in a changing environment, governed today by sustainability goals. In such conditions, always appear new factors of influence and OC itself can exert a powerful impact on specific features of the organizational environment. The methodological approach comprises and follows four phases developed by the authors in accordance with recent and similar research. Main findings suggest that the interest of authors along time has fallen on the impact of OC at first rather than of OC determinants. Also there are many differences in terms of authors, sources, international cooperation, keywords and impact of scientific research between documents regarding the determinants of OC and documents related to the impact exerted by OC.
