Abstract. We examined the negative outcomes, particularly social costs that result when a person harms their group by performing poorly, and whether self-compassion could buffer against these negative outcomes. In Studies 1 and 2, participants performed poorly and harmed their group or performed equal to their group. Harmful poor-performing participants felt more burdensome, experienced more negative affect, felt more ostracized, anticipated more exclusion, and felt lowered self-esteem than equal-performing participants. Studies 3 and 4 disentangled poor performance from harming a group. Poor-performing participants either harmed the group or caused no harm. Harmful poor-performing participants felt more burdensome and anticipated more exclusion, indicating the additional social consequences of a harmful poor performance over a non-harmful performance. Across studies, trait self-compassion was associated with reduced negative effects.

Optimal Bidding

In the recent electricity market framework, the profit of the generation companies depends on the decision of the operator on the schedule of its units, the energy price, and the optimal bidding strategies. Due to the expanded integration of uncertain renewable generators which is highly intermittent such as wind plants, the coordination with other facilities to mitigate the risks of imbalances is mandatory. Accordingly, coordination of wind generators with the evolutionary Electric Vehicles (EVs) is expected to boost the performance of the grid. In this paper, we propose a robust optimization approach for the coordination between the wind-thermal generators and the EVs in a virtual<br>power plant (VPP) environment. The objective of maximizing the profit of the VPP Operator (VPPO) is studied. The optimal bidding strategy of the VPPO in the day-ahead market under uncertainties of wind power, energy<br>prices, imbalance prices, and demand is obtained for the worst case scenario. A case study is conducted to assess the e?effectiveness of the proposed model in terms of the VPPO's profit. A comparison between the proposed model and the scenario-based optimization was introduced. Our results confirmed that, although the conservative behavior of the worst-case robust optimization model, it helps the decision maker from the fluctuations of the uncertain parameters involved in the production and bidding processes. In addition, robust optimization is a more tractable problem and does not suffer from<br>the high computation burden associated with scenario-based stochastic programming. This makes it more practical for real-life scenarios.<br>

The author analyses Grzegorz Królikiewicz’s Trees (1994) in two ways: as a metaphor of the Polish post-1989 transition, and as an eco-horror presenting the complexity of relations between human and plant world. This binary interpretation attempts to answer the question about the causes of the failure of Trees as a film project. The film itself may also be interpreted as a story about historical conditions that affect the ability to create visual representations of the social costs of political changes, as well as ecocritical issues.
