Against Capital Punishment offers an innovative proceduralist argument against the death penalty. Worries about procedural injustice animate many popular and scholarly objections to capital punishment. Philosophers and legal theorists are attracted to procedural abolitionism because it sidesteps controversies over whether murderers deserve death, holding out a promise of gaining rational purchase among death penalty retentionists. Following in this path, the book remains agnostic on the substantive immorality of execution; in fact, it takes pains to reconstruct the best arguments for capital punishment and presumes the appropriateness of execution in limited cases. At the same time, the book contends that the possibility of irrevocable mistakes precludes the just administration of the death penalty. The heart of Against Capital Punishment is a philosophical defense of the well-known irrevocability argument, which analyzes the argument’s premises, establishes their validity, and vindicates them against objections. The central claim is that execution violates the principle of remedy, which requires legal institutions to remedy their mistakes and to compensate those who suffer from wrongful sanctions. The death penalty is repellent to the principle of remedy by dint of its irrevocability. The incompatibility of remedy and execution is the crux of the irrevocability argument: because the wrongly executed cannot enjoy the obligatory remedial measures, execution is impermissible. Against Capital Punishment also reveals itself to be free from two serious defects plaguing other versions of proceduralism: the retributivist challenge and the problem of controversial consequences.

Urban freshwater lakes play an indispensable role in maintaining the urban environment and are suffering great threats of eutrophication. Until now, little has been known about the seasonal bacterial communities of the surface water of adjacent freshwater urban lakes. This study reported the bacterial communities of three adjacent freshwater lakes (i.e., Tangxun Lake, Yezhi Lake and Nan Lake) during the alternation of seasons. Nan Lake had the best water quality among the three lakes as reflected by the bacterial eutrophic index (BEI), bacterial indicator (Luteolibacter) and functional prediction analysis. It was found that Alphaproteobacteria had the lowest abundance in summer and the highest abundance in winter. Bacteroidetes had the lowest abundance in winter, while Planctomycetes had the highest abundance in summer. N/P ratio appeared to have some relationships with eutrophication. Tangxun Lake and Nan Lake with higher average N/P ratios (e.g., N/P = 20) tended to have a higher BEI in summer at a water temperature of 27 °C, while Yezhi Lake with a relatively lower average N/P ratio (e.g., N/P = 14) tended to have a higher BEI in spring and autumn at a water temperature of 9–20 °C. BEI and water temperature were identified as the key parameters in determining the bacterial communities of lake water. Phosphorus seemed to have slightly more impact on the bacterial communities than nitrogen. It is expected that this study will help to gain more knowledge on urban lake eutrophication.

The paper deals with voltage profiles in a power system. The analysis of these profiles is important due to the requirement that the Root-Mean-Squared (RMS) values of nodal voltages should be within certain ranges, as well as to ensure desired power flows in a power system. In both cases, it is desirable to indicate points in a power system where it is reasonable to apply remedial measures to meet the requirements for RMS values of nodal voltages, or to effectively control the power flows in a power system. In general, candidate nodes for remediation are established based on operational experience or measurement data from a certain time point (sometimes from several time points). The paper presents a method that provides a basis for determining the aforementioned candidate nodes based on the behavior of a system over a certain period of time, which is an unquestionable advantage of this proposal. In order to achieve the abovementioned goal, the method provides for the analysis of propagation of voltage RMS value deviations in a power system. The analysis of correlational relationships between the RMS values of nodal voltages is used for this. After presentation of the theoretical background, the new original method is described in the paper. Then, case studies showing the utilization of that method are presented. At the end of the paper, features of the proposed method are enumerated.
