How it started... How it's going....
We seem to have gone from "Defend Migrant Rights" to "More Migration Cops".
We have gone from "Economic Justice" and tax-raises to "Economic Stability" (which presumably means "no change")
We have gone from "Radical devolution of power" and "Social Justice" to "Crack down on anti-social behaviour"
Common Ownership, Union Rights, and Promotion of Peace dropped entirely.

The rise of right-wing extremism fosters excessive nationalism, economic decline, the undermining of democracy, resulting in fear, autocracy and poverty. It's a tragedy.

Russia Leverages Its Nuclear Expertise in Africa
Despite Western sanctions, Russia is leveraging its nuclear expertise to forge economic alliances in Africa, capitalizing on the continent's energy needs and ambitions for clean energy development.

The role of the conservative elite in the Nazi rise to power
The conservative elite were the old ruling class and new business class in Weimar Germany.
Throughout the 1920s they became increasingly frustrated with the Weimar Republic’s continuing economic and political instability, their lack of real power and the rise of communism.
They believed that a return to authoritarian rule was the only stable future for Germany which would protect their power and money.

In light of NY's awful governor torpedoing #CongestionPricing, a few facts worth noting:
1) Transportation is the largest share (28%) of the US's #CarbonEmissions by sector. The next biggest sector, electricity, has been shrinking for the past two decades:

The national greenhouse gas inventory is developed each year to track trends in U.S. emissions and removals. Find emissions by source, economic sector and greenhouse gas.

Throwing some things out here that might be naive. Oh well. Why don't some democratically minded billionaires fight rightwing billionaires? Is it because billionaires by their very nature are all anti-democratic? I heard of one once that wasn't, but one hardly stands a chance against many with the same economic power among them. Why though would many others cede power and money to one, two, or a few? A coalition could quickly end preeminant power of a billionaire. They should.

Generalized Principal-Agent Problem with a Learning Agent
Generalized principal-agent problems, including Stackelberg games, contract design, and Bayesian persuasion, are a class of economic problems where an agent best responds to a principal's committed strategy. We study repeated generalized principal-agent problems under the assumption that the principal does not have commitment power and the agent uses algorithms to learn to respond to the principal. We reduce this problem to a one-shot generalized principal-agent problem with an approximately-be…

There was a period during the industrialization where people fought against the machines — as there was no underlying theory or class consciousness answering why their working conditions were so abhorrent, people thought the problem was the machine, not capitalists who built them.
You may laugh at that, but just remember how many people think getting “replaced by an AI” is a real threat caused by technological development, not our economic system and the people that power it.

Light-Emitting Diodes for Energy Harvesting
Energy harvesting is gaining substantial relevance in the realm of ultra-low-power electronics and Internet-of-Things devices with limited access to classic power sources. Several harvesting approaches are available, depending on the energy source; among them, photovoltaic devices benefit from the highest energy density. However, the inclusion of a dedicated photovoltaic cell in a low-power system may result in increased costs and complexity, thus hampering economic sustainability. Conversely, …

Robust Economic Dispatch with Flexible Demand and Adjustable Uncertainty Set
With more renewable energy sources (RES) integrated into the power system, the intermittency of RES places a heavy burden on the system. The uncertainty of RES is traditionally handled by controllable generators to balance the real time wind power deviation. As the demand side management develops, the flexibility of aggregate loads can be leveraged to mitigate the negative impact of the wind power. In view of this, we study the problem of how to exploit the multi-dimensional flexibility of elas…

Prediction of Space Weather Events through Analysis of Active Region Magnetograms using Convolutional Neural Network
Although space weather events may not directly affect human life, they have the potential to inflict significant harm upon our communities. Harmful space weather events can trigger atmospheric changes that result in physical and economic damages on a global scale. In 1989, Earth experienced the effects of a powerful geomagnetic storm that caused satellites to malfunction, while triggering power blackouts in Canada, along with electricity disturbances in the United States and Europe. With the so…

Chance-Constrained Economic Dispatch with Flexible Loads and RES
With the increasing penetration of intermittent renewable energy sources (RESs), it becomes increasingly challenging to maintain the supply-demand balance of power systems by solely relying on the generation side. To combat the volatility led by the uncertain RESs, demand-side management by leveraging the multi-dimensional flexibility (MDF) has been recognized as an economic and efficient approach. Thus, it is important to integrate MDF into existing power systems. In this paper, we propose an …

Renewable Technologies: Advantages, Disadvantages and Strategic Policies
This article evaluates the types of typical renewable energy technologies separately. Switching from fossil-fuel-based technology to green energies is time-consuming and requires a high investment cost. In addition, the production of energy by new technology may cause the deactivation of some power plants, which will result in unemployment and negative economic growth impacts. In this research, the policies of different countries have been investigated, and strategies for developing these resou…

A Benchmark for the Application of Distributed Control Techniques to the Electricity Network of the European Economic Area
The European Economic Area Electricity Network Benchmark (EEA-ENB) is a multi-area power system representing the European network of transmission systems for electricity to facilitate the application of distributed control techniques. In the EEA-ENB we consider the Load Frequency Control (LFC) problem in the presence of renewable energy sources (RESs), and energy storage systems (ESSs).
