Spillovers have attracted wide attention in the areas of research in economics during the past decades. The reason for the interest in the topic lies in their important role in endogenous growth theory and the explanation of productivity growth. This paper investigates the spatial spillover of different types of public infrastructure on economic growth across EU-28 NUTS-II regions during 1995-2015. Particularly, we developed the previous studies by consedeing spillover in all types of the GDP sector composition including agriculture, industry, and services. The spatial Durbin panel data model is employed to consider spatial spillovers of both public infrastructure and economic growth. Empirical results show the positive spatial spillovers of communication infrastructure in all the sectors. The spillover effect of transport infrastructure is positive in the service and agricultural sector, whereas it is negative in the industry sector. Moreover, the spillover effect of local infrastructure is insignificant in all three sectors. Finally, we find significant evidence of positive geographical spillovers of economic growth implying spatially-growth dependency of regions to growth rate of neighboring regions.

It appears that English Proficiency Test (EPT) as a high stake test plays a key role in addressing many aspects of the educational system and individuals' lives. This paper aimed to represent Iranian non-English PhD students’ perceptions regarding their learning and testing preferences, and to investigate the relationship between educational consequences and psychological consequences of EPT among Iranian non-English PhD students. To reach the goals, two attitudinal researcher-made questionnaires developed and validated (in Persian) at five point Likert-scale format scaling from 1-5 (strongly disagree to strongly agree); subsequently, pilot study was conducted and then the instruments were distributed among 252 participants via online administration throughout Iran. The analyzed results by the software package of SPSS, version 24 showed that deep learning had the highest mean among other subscales and item 3 in testing preferences which was related to creativity hit the lowest mean score. Moreover, the results confirmed that there was a significant and positive relationship between educational consequences and psychological consequences.

The high transparency and ability of consumers to transmit advertising content quickly in the modern age require that organizations consider authenticity and interaction with customers among their top priorities and combine consumer-generated advertising (CGA) with their own marketing strategies in order to respond to these priorities. This study aims to investigate the factors affecting consumers' attitudes and willingness toward consumer-generated advertising and its effect on brand loyalty and attachment. This is an applied study conducted using the descriptive correlational survey method. Its statistical population consists of dairy consumers of Kalleh Company in Mazandaran Province. A total of 460 questionnaires were distributed by stratified random sampling and descriptive and inferential statistics was used for data analysis. Structural equation modeling and Smart PLS2 were used to test the hypotheses. The reliability of the questionnaires was determined by Cronbach's alpha test and composite reliability coefficient. Results showed that brand attachment had a significant positive effect on attitude toward advertising production and willingness to participate in advertising production. Attitude toward advertising production has a significant positive effect on willingness toward CGA as well as on brand loyalty. It was also shown that brand attachment has a significant positive effect on loyalty. The rapid changes in technology and the development of effective advertising in the modern businesses require defining the concept of CGA, which is addressed in the present study. Also, based on the results of this study, brand attachment increases customers’ willingness toward and participation in CGA. An increase in customers' willingness and involvement in advertising production will also increase their loyalty.
