Gothie et Crimee de 750 a 830 dans les sources ecclesiastiques et monastiques grecques
В статье рассматриваются сообщения о Крыме или Крымской Готии, содержащиеся в «Житии Иоанна Готского», и связанные с ними свидетельства из одновременных, или созданных несколько позже церковных и монашеских источников. Удаленные от империи города крымского побережья и Крымская Готия играли определенную роль в политической и религиозной жизни Константинополя
Walk the talk: shareholders' soft engagement at annual general meetings
The right to ask questions and voice their opinions at annual general meetings (AGMs) represents one of the few avenues for shareholders to communicate directly and publicly with the firm’s management. Examining AGM transcripts of U.S. companies between 2007 and 2021, we find that shareholders actively express their concerns about environmental, social and governance (ESG) issues in accordance with their specific relationship with the company. Further, they are also demonstrably more vocal about ESG issues at AGMs of firms with poor sustainability performance. What is more, we show that this soft engagement translates into a more negative tone which, in turn, results in lower approval rates for management proposals. Shareholders' soft engagement at AGMs is hence an effective way to "walk the talk"
Can electricity pricing leverage electric vehicles and battery storage to integrate high shares of solar photovoltaics?
Leveraging electric vehicles with controlled charging has the potential to advance the integration of high shares of residential solar photovoltaics. Time-varying electricity pricing is a promising tool to control EV charging indirectly through price signals, but also affects the diffusion and usage of other residential technologies. In this article, we develop an agent-based model to simulate California’s residential market for electric-vehicle charging, and the adoption of solar photovoltaics and battery storage, between 2005 and 2030. We show that time-of-use and hourly rates have a substantial impact on the further diffusion and integration of these technologies. Time-of-use rates trigger the adoption of battery storage, but over-coordinate electric-vehicle charging. Hourly rates, in contrast, slow down the diffusion of solar photovoltaics temporarily, but concentrate electric-vehicle charging around midday, thereby reducing the need for fast-ramping generation capacity and carbon emissions. Using real-world driving patterns, we show that 80% of EVs shift charging to midday hours with home charging alone. However, EVs only reduce the need for ramping capacity and thus advance PV integration, when users also have access to workplace and public charging. Further, we demonstrate that electric vehicles mitigate the increase in retail electricity prices, and thus counteract the utility death spiral. Our results indicate that controlling EV charging with electricity pricing decreases utility costs but increase retail electricity prices.ISSN:0306-2619ISSN:1872-911
Are sustainability-linked loans designed to effectively incentivize corporate sustainability? A framework for review
The issuance of sustainability-linked loans (SLLs) has grown exponentially in recent years. Using a scoring methodology, we examine the underlying key performance indicators of a large sample of SLLs and analyze whether their design creates effective incentives for improving corporate sustainability performance. We demonstrate that the majority of loans fails to meet key requirements that would make them credible instruments for generating effective sustainability incentives. These findings call into question the actual sustainability impact that may be achieved through the issuance of ESG-linked debt
