This article examines the use of emergency intervention for child protection in England by the police and social services to establish when and why powers are used and what subsequently happens. It is based on two studies in England between 1998 and 2004: 1) The Police Protection Study (PP), which examined the use of police protection through a survey of 16 (of the 43) police forces in England and Wales and record reading (311 cases) and interviews (57) in eight forces. 2) The Emergency Protection Orders (EPO) study, which examined EPO applications though a national survey of courts, an analysis of cases (86) from six social services departments, and interviews (78) with social workers, lawyers, court staff and magistrates. There are wide variations in the use of emergency powers. The police act independently and in response to social workers' requests. Social workers resort to emergency powers in well‐known, serious cases when parents refuse co‐operation. EPOs are followed by care proceedings.

This chapter generally concerns how elements of liberal democratic constitutional discourse have functioned to normalize emergency and possible state of exception governance during the COVID-19 pandemic. More specifically, the chapter focuses on the transference of legislative power to the executive under conditions of emergency rule and how it is possible for delegated emergency lawmaking to operate beyond the limits of what is constitutionally permissible; thus, triggering a state of exception. The chapter uses the deployment emergency rule during the pandemic in The Bahamas as a case study to show how ambivalence and legal uncertainty were the two principal drivers of the normalization process produced by elements of constitutional discourse, and then further explains how constitutionalism, generally, and in its dysfunctional application, can reinforce the processes normalizing emergency and possible state of exception governance.

Purpose – This chapter aims to analyze the pandemic situation in a legal and political point of view, to find what measures have been adopted by States to face the spread of the contagion, and whether those measures have been determinant in the redefinition of democracy. Emergency dispositions were enacted when an “emergency state” was declared, containing a series of dangerous elements for the correct application of the rule of law.

Methodology/Approach – The approach considers a “pluralistic methodology” that refers to a comparative law study, but also uses the approach of political science, history of institutions, and sociology. From this point of view, this chapter regards similarities and differences, between two or more legal systems, as coincidences or dissonances, comparing cases in a diachronic and synchronic way at the same time to evidence what is the democratic erosion.

Findings – This chapter doesn’t want to provide a mere chronicle of what happened during the COVID-19 situation, but it finds that in some peculiar cases emergency affected a degeneration of democratic institutions, and an acceptance of a new model of state, with hypertrophic executives, weak legislative bodies, not equilibrated balance of fundamental rights, and a rise of technocracy.

Originality/Value – Based on other studies focused on state-by-state oversights during the pandemic, our theory intends to enlighten the COVID-19 as a “black swan” in the international political and legal scenario, or a sort of turning point in an inevitable and unstoppable transformation of the state model that appears to aspire to a return of some autocratic attitudes.

Power outages which may be triggered, for example, by natural hazards and system failures are a common phenomenon, associated with large impacts on society including the healthcare sector. Minimising adverse impacts effectively requires an analysis of possible impacts and the identification of measures aiming at reducing vulnerability and increasing resilience.

To systematically identify impacts as well as preparation, mitigation and recovery (PMR) measures, a moderated workshop with participants representing different healthcare sub‐sectors in Germany was conducted and complemented by semi‐structured interviews and a thorough analysis of literature. Impacts were determined for three scenarios of power outage duration, <8, 8‐24 and >24 hours.

Whereas hospitals are in general well prepared with respect to shorter outages, due to obligatory emergency power in Germany, outpatient medical care, nursing homes (NH) and, in particular, home‐care nursing are early affected. Failure of these sub‐sectors puts additional strains on hospitals. If outages last more than one day and are associated with failure of other critical infrastructures (CIs), especially water supply, hospitals may be severely affected. Effective preparation and mitigation measures identified based on a facility‐specific impact analysis, as well as good cooperation between actors, may reduce impacts.

The largely case‐study‐based literature is complemented by a systematic and extensive analysis of direct and indirect impacts on the main healthcare sub‐sectors in Germany, followed by an identification of specific PMR measures. As a novelty outage duration is explicitly accounted for. Also, interdependencies between the healthcare sub‐sectors as well as dependencies on other CI are considered.

This paper challenges and expands commonplace assumptions about problems of time and temporality in emergencies. In traditional emergency powers theory “emergency time” is predominantly an “exceptional time.” The problem is that there is “no time” and the solution is limited “in time”: exceptional behavior is allowed for a special time only, until the emergency is over, or according to formal sunset clauses. But what is characteristic of many emergencies is not the problem of “no time” but the ways in which time is legally structured and framed to handle them. Using the Israeli High Court of Justice 1999 decision on the use of physical interrogation methods under conditions of necessity, this paper illustrates how legally significant emergency-time structures that lay beyond the problematic of exceptional time, gravely implicate the way that “exceptional measures” are practiced and regularized.

The purpose of this paper is to examine the impact of renewable energy on the power supply chain and to study whether the renewable generator or the power grid that purchases power from the power spot market is better when the actual generation of renewable energy is insufficient. The authors want to compare and analyze the different power supply chain operation modes and discuss the optimal mode selection for renewable energy generator and power grid in different situations.

This paper studies the grid-led price competition game in the power supply chain, in which the power grid as a leader decides the price of transmission and distribution, and generators determine the power grid price. The renewable energy power generator and the traditional energy power generator conduct a price competition game; on the other hand, the power grid and power generators conduct Stackelberg games. The authors analyze the power supply of single power generator and two power generators, respectively, and research on the situation that the renewable energy cannot be fully recharged when the actual power generation is insufficient.

The study finds that both renewable and traditional power grid prices decline as price sensitivity coefficient of demand and installed capacity of renewable energy generators increase. Power grid premium decreases as the price sensitivity coefficient of demand increases, but rises as the installed capacity of renewable energy generator increases. When there is a shortage of power, if the installed capacity of renewable energy is relatively small and price sensitivity coefficient of demand is relatively large, the grid purchases the power from power spot market and shares cost with renewable energy generators, leading to higher expected profits of the renewable energy generators. On the contrary, the renewable energy generators prefer to make up power shortage themselves. For the power grid, purchasing the power by the renewable energy generators when there is a power shortage can bring more utility to the power grid when the installed capacity of renewable energy is lower and the demand price sensitivity coefficient is higher. When the installed capacity of renewable energy is high and the price sensitivity coefficient of demand is moderate, or the installed capacity of renewable energy is moderate and the demand price sensitivity coefficient is high, a generator that simultaneously possesses two kinds of energy source will bring more utility to the power grid. If the installed capacity of renewable energy and the demand price sensitivity coefficient both are small or the installed capacity of renewable energy and the price sensitivity coefficient of demand both are large, the power grid prefers to purchase the power by itself when there is a power shortage.

The goal of our paper analysis is to explore the implications of the theoretical model and address the series of research questions regarding the impact of the renewable energy on the power supply chain. The results of this study have key implications for reality. This paper sheds light on the power supply chain operation mode selection, which can potentially be used for the renewable energy generators to choose their operating mode and can also help traditional energy generators and power grid enterprises maximize their utility. This paper also has some references for the government to formulate the corresponding renewable energy development policy.

This paper studies the power operation mode under the uncertainty of supply and demand, and compares the advantages and disadvantages of renewable energy generator that makes up the shortage or the power grid purchases the power from power spot market then shares cost with the renewable energy generator. This paper analyzes the power grid-led coordination problem in a power supply chain, compares and analyzes the price competition game model of single power generator and dual power generators, and compares the different risk preferences of power grid.

In the USA, the Federal Emergency Management Agency (FEMA) provides support to State and local governments in fulfilment of their responsibilities for preparedness, response, recovery and mitigation of disasters. One method FEMA has used to support State and local emergency communication functions was to sign and implement a Memorandum of Understanding with the American Radio Relay League (ARRL) for amateur radio operators to provide electronic communications for State and local governments in disasters. The Federal Communications Commission (FCC) has licensed more than 600,000 amateur radio operators in the USA. The national organization of amateur radio operators called the American Radio Relay League (ARRL) was formed in 1914. More than 80,000 of these amateurs have registered their availability for emergency communications in disasters in the ARRL’s Amateur Radio Emergency Service (ARES). Amateur radio operators have been providing communications in natural disasters such as floods, hurricanes and earthquakes since 1910. Since amateur radio operation was prohibited during the years of both World Wars I and II, FEMA has sponsored a new branch of the amateur service called Radio Amateur Civil Emergency Service (RACES). RACES operators are authorized to operate if the President invokes his War Emergency Powers while all other amateur operation would be silenced. Examines the role of amateur radio in providing emergency electronic communications for disaster management and explores future contributions.

The purpose of this paper is to define reliability requirements to be imposed on electric engines to assure similar or higher value of mean time between failures (MTBF) for mixed piston-electric propulsion configurations when compared to classic and unconventional piston engine configurations.

Reliability estimation was done using mathematical model of safety of light aircraft commercial operations. The model was developed on the basis of Federal Aviation Administration and National Transport Safety Board data. The analysis was conducted for numerous piston and electric configurations. It allowed comparison of selected solutions and definition of relation between electric engine MTBF and MTBF calculated for entire mixed piston-electric propulsion system.

It was found that, from reliability point of view, mixed piston-electric engine propulsion is attractive alternative for classic single- and twin-piston configuration. It would allow to at least doubling of MTBF for propulsion without increase of operational cost.

Rationale behind exploiting electric propulsion in aviation is provided. Relation between electric engine reliability and entire propulsion reliability was identified and defined. Minimum requirements concerning MTBF value for electric engine application in aviation was assessed. Conclusions from this study can be used for definition of requirements for new aircraft and by the regulatory authorities.

Originality consists in use of real accident statistics included in mathematical model of safety for assessment of MTBF for various classic and novel piston and piston-electric engine configurations of light aircraft. Output from the study can be exploited by the industry.
