The article proposes to analyze cyber-situational awareness of an energy facility in three stages. There are i) analysis of cyber threats to the energy infrastructure; ii) modeling of extreme situations scenarios in the energy sector caused by the implementation of the cyber threats; iii) risk assessment of the cybersecurity disruption to energy infrastructure. Three methods are presented, corresponding to each stage. The authors propose to apply semantic modeling methods to analyze the impact of cyber threats to energy facilities, taking into account energy security within the presented approach. Such methods show their effectiveness in the absence or incompleteness of data for modeling the behavior of systems, which defies formal description or accurate forecasting. The presented approach to the cyber situational awareness analysis of energy facilities considered as a synthesis of cybersecurity and situational awareness studies, characterized by the use of semantic modeling methods.

The paper considers the violation of cybersecurity as a possibility of a real impact (intentional or accidental) from cyberspace on the physical infrastructure of a digital energy facility. In energy security studies, such impacts are considered as extreme situations, including critical and emergency situations. A model of scenarios of extreme situations in the energy sector caused by cyber threats using Bayesian Belief Network and the stages of modeling are considered in more detail. The five main stages are i) modeling cyber threats vectors of intrusion and advance towards the target asset; ii) modeling an attack on a target system in the technological segment of the local area network; iii) modeling technogenic threats to energy security caused by cyber threats; iv) modeling consequences at the level of the facility system; v) modeling consequences at the level of the infrastructure. This approach allows one to build cause and effect relationships from vulnerabilities in the cyber environment to the consequences. Modeling stages are aimed at increasing the level of cyber situational awareness, which, in turn, related with energy security issues.

The Impact

This paper discusses the interface between violence in the Niger Delta, global energy security and amnesty granted to armed groups by the Nigerian government. The author notes the impact of the violence on energy infrastructure and brings to the fore how the violence endangers energy security. Thus far, a major concern is that the amnesty program will fail because it was not preceded by negotiations between the government and combatants. The author questions this view and points outs that before the amnesty proclamation, several negotiations through committees and commissions involving stakeholders had been done. The paper thus argues that it cannot be entirely correct to conclude that there were no negotiations before the amnesty program was proclaimed. Further, it argues that the issue of negotiation cannot be as important as the failure of government to tackle the fundamental issues which triggered the conflict. The deepening of the country’s democracy to ensure that votes count at elections is seen as the most likely option to guarantee the success of the amnesty program and secure the region and energy security.

The Relationship

While populism challenges the pluralism and technocratic expertise on which public bureaucracies are based, extant scholarship has overlooked its effects on accountability processes. In particular, it neglects the impact of anti-elite rhetoric, characterized by what can be regarded as “emotionalized blame attribution,” on the thinking and behavior of accountability actors. Responding to this gap, this article examines the impact of this distinctive form of populist rhetoric on accountability relationships within the bureaucratic state. It identifies three “stages” whereby these populist pressures challenge accountability relationships, threaten the reputation of accountability actors, and result in alternative accountability practices. In doing so, the article provides a roadmap for assessing the impact of anti-elite rhetoric on accountability actions.

Background: Review-based research is needed which can establish the psychosocial outcomes and mechanisms of “storytelling and sharing” interventions for people with stroke. This information will act to inform the value and development of such interventions. Methods: An integrative review was conducted in three stages: (a) a systematic search strategy was undertaken to focus on articles between 2009 until January 2020 to locate articles the considered storytelling and sharing interventions for people diagnosed with stroke; (b) critical appraisal was undertaken to assess study quality; and (c) synthesis within three stages including data reduction, data display and conclusion. Results: Fourteen articles (including 727 participants) were identified that met the eligibility criteria. Five themes were identified that represented the outcome and mechanisms that appeared to be associated with a stroke intervention. These included introducing the concept of hope and learning to be positive, the enhanced ability to cope, the impact of loneliness and social interaction, impact on emotions, depression and related emotions such as fear. Conclusions: Storytelling interventions appear to impact loneliness, introduce positivity and hope and enable coping through knowledge exchange. The main mechanisms which appeared to influence these outcomes were social comparisons and social control.

The risks of technological accidents in the energy sector and their potentially disastrous effects have been analyzed over the past decades, and are nowadays generally recognized to constitute a key factor in an encompassing assessment of energy security. In contrast, the issue of intentional attacks on energy infrastructures has received increased attentionmore recently, particularly due to growing dependence of energy imports fromand transit routes through regions considered less reliable and politically stable. Both types of risks, however, illuminate different vulnerabilities. Therefore, the focus of the present analysis was on these two risk categories: accidents and intentional attacks in the energy sector. Risk assessment resultswere based on quantitative data from the databases ENSAD (Energy-related Severe Accident Database) and EIAD (Energy Infrastructure Attack Database). Evaluations examined similarities and differences between technological accidents and intentional attacks in terms of frequencies and consequences, considering time-series trends and regional patterns. A key difference is that accidents are typically rare and independent events, whereas intentional attacks are often multiple events and concentrated both in time and space, resulting in distinct hotspots. Concerning consequences, the severity distribution for accidents generally stretches over a broad range, with low-probability high-consequence events being an important factor of both energy chain performance and as a measure of risk aversion. On the other hand, these types of consequences are usually less important for intentional attacks because targeted energy infrastructures are often of “linear” nature (e.g. pipelines and transmission lines) that are difficult to protect and usually lead through remote areas with low population density. However, when frequently attacked substantial business and supply disruptions can occur. In summary, the joint analysis of accidents and intentional attacks provides a comprehensive and complementary approach on two types of risks that have rather different properties, but are essential in an energy security perspective.

The Impact

The events of September 2001, 2001, plus the events' technical and political aftermath have helped to identify an unfortunate lack of research into building evacuation. The relative dearth of research is ironic given evacuation's central role in mitigation for a range of emergencies and its prominence in environmental design requirements in building codes and standards. The field of human factors has much to offer, for example, in a philosophical or strategic focus on human-centered design as well in more-prosaic issues such as exit stair width and handrail provision. Much of the available research addresses fairly low-level ergonomic issues such as exit stair width in relation to egress capacity and the impact on evacuation time. in addition to more-sophisticated research into the relatively simple issues, ahead lies more-difficult research relating to strategic issues and the provision of information to building occupants in emergencies, occupants' situational awareness generally, and the many social interactions—in seldom-considered environmental contexts—that are at the heart of major evacuations of large buildings such as in the case of the World Trade Center.

Hennepin Energy Recovery Center (HERC) is a waste to energy facility owned by Hennepin County and operated by Covanta Energy. HERC has been in operation since 1989. The facility burns 365,000 tons of residential and commercial solid waste per year and generates about 34 mega-watts of electricity that is sold to Xcel Energy. HERC is located on the north side of downtown Minneapolis in the Historic Warehouse District, a neighborhood that is changing from industrial to a more commercial/residential mix with loft conversions and construction of new condominiums. The Minnesota Twins baseball team is also siting a new stadium in the parking lot immediately southeast of the facility. The potential for odors from the tipping floor of the facility affecting the neighborhood has become more of a concern due to the changes in the neighborhood. In March 2004 the County began an odor study. This included developing baseline information on odors from HERC and from the surrounding community by conducting daily odor monitoring at select points on the facility property and throughout the community: • Determining how far odors from HERC migrate into the community. • Quantifying detected odors using a Nasal Ranger. • Determining the factors that contribute to these odors. • Developing a method of controlling these odors. • Continued monitoring to determine the impact of mitigation methods. Odors detected were characterized as garbage odors, garbage-related odors, and neighborhood odors. Baseline data showed that while garbage odors from HERC were mostly undetectable beyond the perimeter of the property, there was room for improvement in decreasing the presence and intensity of these odors. The tipping hall was designed to operate under negative pressure to control odors, however the entrance and exit doors were always open and a negative pressure could not be maintained.

In the early 2020s the worlds transition from carbon-intensive to climate-neutral energy use has already become a discernible and a difficult-to-reverse process. With Joe Bidens election as US president, the United States have returned to the Paris Climate Agreement and have become a key driver of this process (along with the EU and China). As a result, the international community has reached a consensus on the ongoing energy transition. This process will require considerable effort and may take several decades. Nevertheless, the impact of energy transition on traditional approaches to energy security, which emerged largely as a result of the global oil crises of the 1970s and 1980s and are centered around the supply of fossil fuels, is already a relevant research topic. This problem is examined relying on the relevant terminological, theoretical and factual material. The article concludes that energy transition will ultimately undermine the carbon paradigm that has underpinned energy security policies since the 1970s. Rapid development of renewable and other low-carbon energy sources will certainly remove key energy security risks of energy importers and, possibly, allow them to achieve energy independence. However, a post-carbon era may also generate new risks. For countries that rely heavily on oil, gas and coal exports, energy transition will result in the loss of markets and revenues. It may present an energy security threat for them as well as it will require a costly and technologically complex process of the energy sector decarbonization. Some exporters, especially those with high fuel rents and insufficient financial reserves, may face serious economic and social upheavals as a result of energy transition. The EU and the US energy transition policies reflect provisions of all three fundamental international relations theoretical paradigms, including realism. This means that the EU and the US policy, aimed at promoting climate agenda, may be expected to be rather tough and aggressive. China as the third key player in energy transition is still following a liberal course; however, it may change in the future.

We describe the uncertainties of altimetry-predicted bathymetry models and then quantify the impact of this uncertainty in tsunami hazard assessments. The study consists of three stages. First, we study the statistics of errors of altimetry-predicted bathymetry models. Second, we employ these statistics to propose a random field model for errors anywhere. Third, we use bathymetry samples to conduct a Monte Carlo simulation and describe the tsunami response uncertainty. We found that bathymetry uncertainties have a greater impact in shallow areas. We also noted that tsunami leading waves are less affected by uncertainties.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/zzL_XWWAQ7o
