CROWDFUNDING AS AN ALTERNATIVE FINANCING FOR SMES AND START-UPS IN MALAYSIA: AN INTRODUCTORY NOTE FROM THE LEGAL PERSPECTIVE

Small and Medium Enterprises (SMEs) and start-ups have consistently contributed to a country’s tax revenue, technology advancement, and innovation, job creation as well as economic outputs. However, they are facing great challenges or setbacks in securing funding from external sources. To overcome the fundraising issues or financing lacuna, many entrepreneurs have resorted to crowdfunding as an alternative source of their equity or debt financing. Crowdfunding, being a significant aspect of the recent fintech innovation and digital disruption, has been put under the spotlight and received high expectations from all stakeholders to be an effective solution to SMEs and start-ups. This article would be focusing on crowdfunding with financial returns, namely, equity crowdfunding (ECF) and crowdlending/peer-to-peer lending (P2P). The research methodology employed by this article is primarily based on the literature review of various legislations, scholarly articles, research papers, government policies, books, and other publications concerning the ECF and P2P from different disciplines. At the end of this article, the author opined that crowdfunding could be a useful alternative financing method for SMEs and start-ups in Malaysia as it helps the capital formation and bridges the financing gaps for them. Countless benefits could also be offered to the society and economy at large with the proper crowdfunding regulations in place. Upon reviewing the Guidelines on Recognised Markets issued by the Securities Commission Malaysia (Guidelines), the author argues that the Guidelines is a carefully crafted and balanced regulation, albeit there is room for improvement.

Possibility of Using Wind and Solar Sources for Electric Power Generation on Serbian Opencast Coal Mines

The rapid technology advancement and the significant decline of investment costs in wind and solar energy generation have opened up a significant opportunity to build these facilities on closed opencast mines or mines in the phase of closure around the world, where large available areas are almost ideal for such projects. In that sense, it is necessary to give an analysis of the possible application of wind and/or solar energy production in the Republic of Serbia’s mines, as well as the dynamics of such a generally ambitious and long-term project with conceptual solutions.

The Long-Term Impact of the Electorate on the Swiss Electricity Market Transition

The Swiss government, through its Energy Strategy 2050, is engaged on a path to transition Switzerland to become a carbon-neutral country by the year 2050. In this chapter, we look at the impact that the electorate can have on this transition and on the Swiss electricity market. This is done using hybrid agent-based modelling. We model the Swiss electricity market and we add to this a model of the policy-making process. This allows us to study which policy instruments are more likely to be implemented depending on the Swiss electricity market progression and on the policy actors’ interests. The results have shown that the electorate has a limited impact on the policy chosen and on the electricity market. Overall, an environmentally conscious electorate leads policy actors to select the carbon tax as a policy more often. This, however, has the adverse effect to increase the electricity price and increase import dependency in winter. In high demand growth scenarios, the carbon tax policy is not sufficient to stem the construction of gas turbine power plants. We also show that because the electricity model does not consider an extended demand response option or technology advancement, the knowledge gained from this model is limited. This drives the behaviour of the model into scenarios which are unlikely to happen, such as a large increase of the gas turbine power plants. Overall, we conclude that, in their current form, even with an environmentally conscious electorate, the electricity market conditions do not allow Switzerland to reach its emissions targets.

Compact Thermal Imager (CTI) for Atmospheric Remote Sensing

The demonstration of a newly developed compact thermal imager (CTI) on the International Space Station (ISS) has provided not only a technology advancement but a rich high-resolution dataset on global clouds, atmospheric and land emissions. This study showed that the free-running CTI instrument could be calibrated to produce scientifically useful radiance imagery of the atmosphere, clouds, and surfaces with a vertical resolution of ~460 m at limb and a horizontal resolution of ~80 m at nadir. The new detector demonstrated an excellent sensitivity to detect the weak limb radiance perturbations modulated by small-scale atmospheric gravity waves. The CTI’s high-resolution imaging was used to infer vertical cloud temperature profiles from a side-viewing geometry. For nadir imaging, the combined high-resolution and high-sensitivity capabilities allowed the CTI to better separate cloud and surface emissions, including those in the planetary boundary layer (PBL) that had small contrast against the background surface. Finally, based on the ISS’s orbit, the stable detector performance and robust calibration algorithm produced valuable diurnal observations of cloud and surface emissions with respect to solar local time during May–October 2019, when the CTI had nearly continuous operation.
