| Abstract: | This study contributes to the extant literature on the nexus between information and communication technologies (ICTs) and agriculture. Despite increasing attention on the subject, existing studies are sparse on the channels through which ICTs affect the agricultural sector. We use a stochastic impact model extended to the population, affluence and technology regression model to assess both the impact and transmission of ICTs on agriculture in 18 sub-Saharan African countries. The empirical results show that ICT use measured by Internet, mobile and fixed-line telephone penetration boosts the agricultural sector enormously. In addition, the mediation analysis reveals that ICTs not only have a direct positive effect on agriculture but also a positive indirect effect through its impact on financial development and trade openness and a negative indirect effect through energy consumption. However, the total effect is positive and shows that ICTs are supporting the development of the agricultural sector in sub-Saharan Africa. To enhance the positive effects of ICTs on agriculture, governments should design policies to improve access to credit for the private sector, promote liberalization, and provide financial incentives for the development of green and less expensive agricultural technologies. |

| Abstract: | The study tries to evaluate empirically, the impact of ICT and economic growth on CO2 emissions of Tunisia and Morocco for the period 1980-2018, based on the Auto-Regressive Distributive Lag (ARDL) analysis. Findings demonstrate that ICT and economic growth affect positively and significantly the CO2 emissions in the short and long term both in Tunisia and Morocco. However, these direct and negative effects of economic growth and ICT on environmental quality may be decreased by introducing the interaction between ICT and economic growth. So, policy makers should adopt such policies that help to reduce CO2emissions by enhancing the use of ICT for economic growth. |

| Abstract: | The struggle to combat climate change remains complex and challenging. Currently, two climate change approaches, namely, mitigation and adaptation, have been widely supported. These are empirical, requiring further explanation of the main drivers of carbon emissions. This research seeks to tackle this problem by providing a strategy to reduce climate change impacts. This study contributes to the existing empirical literature in several ways. It investigates whether education and information and communication technology (ICT) matter to promote environmental sustainability in the Eastern and Southern Africa. The empirical evidence is based on the third-generation panel unit root test and panel cointegration tests that account for the potential issue of structural breaks in the series. We further dissect the long and short run dynamics using the panel Granger causality approach. Our findings show the possibility of using education and clean technology investment in a complementary strategy for mitigating carbon emissions and promoting environmental sustainability in the sampled countries. |

| Abstract: | Are there career benefits to leaders and followers agreeing about the quality of their leader‐member exchange (LMX) relationship? Is LMX disagreement always detrimental for a follower's career? Can the examination of LMX agreement as a substantive variable help us cast new light on some of the inconclusive findings of past research on LMX and career outcomes? These questions motivate our research. Using theories of social exchange and sponsorship, and responses from 967 leader–follower dyads of Information and Communication Technology (ICT) professionals in seven European countries, we examined the role of LMX agreement on subjective and objective career outcomes. After conducting polynomial regression combined with response surface analysis, we found that both follower‐rated and leader‐rated employability were higher when the leader agreed with the follower at a high level of LMX (versus a low level of LMX). In case of disagreement, strong support was found for leader‐rated employability being higher when the leader's perceptions of LMX exceeded those of their follower. Furthermore, follower‐rated employability was found to mediate the relationship between LMX (dis)agreement and perceived career success, promotions, salary, and bonuses. Support was also found for the mediating role of leader‐rated employability in the case of perceived career success, promotions, and salary but not for bonuses. Our findings highlight the importance of LMX (dis)agreement for career outcomes and further point to the possibility of employability offering an alternative explanation for the mixed findings of past LMX‐career research. |

| Abstract: | While adult learning is a vital component of the European Commission’s lifelong strategy, its incidence decreased in 2020 due to the economic impact of Covid-19. A main reason for such decline lies in the disruption of on-the-job training caused by the pandemic. This study, however, shows that increased participation in online learning activities among adults could at least partially compensate for this situation. Using data from the Eurostat's Community survey on ICT usage in households, we find that in most EU countries Covid-19 is associated with a higher proportion of adults taking online courses. Our results indicate also that the increase has been especially pronounced among women, individuals aged 55 to 64, and less educated adults. Enhanced availability and adoption of electronic devices, increased offer of free or low-cost online courses and the labour market effects of Covid-19 are all likely to have contributed to the rise of online adult learning. |
